The Walls of Thessaloniki (Greek: Τείχη της Θεσσαλονίκης, Teíchi tis Thessaloníkis) are the 4 kilometer-long city walls surrounding the city of Thessaloniki during the Middle Ages and until the late 19th century, when large parts of the walls, including the entire seaward section, were demolished as part of the Ottoman authorities' restructuring of Thessaloniki's urban fabric. The city was fortified from its establishment in the late 4th century BC, but the present walls date from the early Byzantine period, ca. 390, and incorporate parts of an earlier, late 3rd-century wall. The walls consist of the typical late Roman mixed construction of ashlar masonry alternating with bands of brick. The northern part of the walls adjoins the acropolis of the city, which formed a separate fortified enceinte, and within it lies another citadel, the Heptapyrgion (Seven Towers), popularly known by the Ottoman translation of the name, Yedi Kule. In 1988, as part of the Paleochristian and Byzantine monuments of Thessaloniki, the walls were added to the UNESCO World Heritage List because of their outstanding Byzantine architecture.

The Pammegistoi Taxiarches church (Greek: Ιερός Ναός Παμμεγίστων Ταξιαρχών, lit. 'Holy Church of the All-Great Taxiarchs') is a Byzantine church located in the Upper Town of Thessaloniki, Greece. The church was built in the 14th century, and served as a mosque during the Ottoman period, before it was turned back into a church in 1912. The church underwent significant modifications during the 1950s and the 1960s, and unlike other Byzantine churches in Thessaloniki, a new section was added in neo-Byzantine style.

The Church of Hosios David (Greek: Όσιος Δαυίδ) is a late 5th-century church in Thessaloniki, Greece. During the Byzantine times, it functioned as the katholikon of the Latomos Monastery (Greek: Μονή Λατόμου/Λατόμων), and was adorned with rich mosaic and fresco decoration, which was renewed in the 12th–14th centuries. Today, the surviving examples are of high artistic quality, especially the apse mosaic Icon of Christ of Latomos. Under Ottoman rule, the building was converted into a mosque (probably in the 16th century), until it was reconsecrated as a Greek Orthodox church in 1921, thus receiving its present name. In 1988, this monument was included among the Paleochristian and Byzantine monuments of Thessaloniki on the list of World Heritage Sites by UNESCO.

Thessaloniki's Upper Town called Ano Poli (Greek: Άνω Πόλη, [ˈano ˈpoli]) is the old town of Thessaloniki and is located around the city's acropolis north of the city center. The neighborhood is known for its well preserved Byzantine and Ottoman era structures and urban design and as a center for Thessaloniki's poets, intellectuals, and bohemians. Ano Poli is one of the most traditional areas in Thessaloniki. The area preserves much of the Byzantine and Ottoman era city design which was largely destroyed elsewhere in the city in the Great Fire of 1917. It is known for its small stone-paved streets, old squares, and houses in traditional Greek and Ottoman architecture. Ano Poli is the highest part of the city and is dominated by the city's acropolis, a Byzantine and Ottoman era fort known as the Eptapyrgio. What remains of the old city walls still surround Ano Poli and many Ottoman and Byzantine structures such as the church of Profitis Elias, the Church of Saint Nicholas Orphanos, the Taxiarches church, the Byzantine bath, the Church of Saint Catherine, the Vlatades Monastery, the Atatürk Museum, and the Alaca Imaret Mosque still stand in the neighborhood. Other landmarks include the buildings of Villa Moskof and Villa Varvara. During the Ottoman period Ano Poli was the main district for the Turks (Muslims) of the city while Greeks, western Europeans, and Jews lived below around the port. On clear days Mount Olympus, about 80 km (50 mi) away across the gulf, can also be seen towering the horizon.

The Byzantine Bath of the Upper Town (Greek: Βυζαντινά Λουτρά Άνω Πόλης, Vyzantiná Loutrá Áno Pólis) in Thessaloniki is one of the few and best preserved of the Byzantine baths that have survived from the Byzantine period in Greece. It is located on the Theotokopoulou Street in the Upper Old Town of Thessaloniki.The baths date to the late 12th/early 13th century, and functioned continuously until 1940, when they shut down probably due to World War II and the German occupation of Greece. The Byzantine sources do not mention it, hence it is likely that it originally belonged to a monastery complex. In Ottoman times, it was known as Kule Hammam, i.e. "bath of the citadel".The bath's long use led to numerous alterations of the original structure over time. The original architecture follows the typical conventions of Roman baths. The original entrance in the south leads to the rectangular frigidarium rooms, which were used as dressing rooms. Then came two vaulted tepidarium rooms and finally two caldarium rooms. The latter were square in shape and featured hypocausts below the floor. One was covered by a dome supported by an octagonal base with eight windows, the other had a domed ceiling. To the north of the baths was the cistern that provided it with water, with a hearth beneath to warm it. In Byzantine times the building was alternately used by men and women, but in the Ottoman period the bath was divided into exclusively male and female sections, by blocking off each pair of rooms from each other.The bath was one of several in the city—the 14th-century writer Nikephoros Choumnos claims that Thessaloniki had more baths than inhabitants—but is the only surviving in Thessaloniki and the largest and most complete of the handful of Byzantine baths surviving elsewhere in Greece: five ruined public baths—two in Corinth, one in Sparta, one in Paramythia, one in Ioannina Castle—and one each in the monasteries of Kaisariani and Zoodochos Pigi.Although closed since 1940, the bath was subject to neglect and damage during the 1978 earthquakes, and only survived standing through heavy propping up by the 9th Ephorate of Byzantine Antiquities and the protection offered by an external metal sheet covering. In 1988, it was included among the Paleochristian and Byzantine monuments of Thessaloniki on the list of World Heritage Sites by UNESCO.Following four years of restoration work, the bath was re-opened to the public as a museum and cultural space in June 2015.

The Musa Baba Türbe (Greek: Τεκές Μουσά Μπαμπά) is a türbe (mausoleum) from the Ottoman period in the Upper Town of Thessaloniki in Greece, in Terpsitheas Square. It dates to the sixteenth century.

The Church of Saint Nicholas Orphanos (Greek: Ἅγιος Νικόλαος ὁ Ὀρφανός) is an early 14th-century Byzantine church in the northern Greek city of Thessaloniki. Covered in outstanding Byzantine frescoes, the church is inscribed on the UNESCO World Heritage List along with other Paleochristian and Byzantine monuments of Thessaloniki, demonstrating the importance of Thessaloniki in early Christian history.

The National Map Library (Greek: Εθνική Χαρτοθήκη), properly the National Centre for Maps and Cartographic Heritage - National Map Library, is located in Thessaloniki, Central Macedonia, Greece. It was established in 1997 (Law 2466/1997) for the purpose of preserving, archiving, conserving, promoting, and displaying maps, studying the educational, cultural, and social role of maps, collaborating at a scientific and technical level with national and international organizations, organizing permanent and mobile exhibitions accompanied by catalogues, utilising public and private map collections, and organising seminars and conferences. Since February 1999 the National Map Library has been housed in a two-storey listed building in the Upper Town (Ano Poli). On the ground floor are the scientific and administrative departments and on the first floor there is a permanent exhibition space which hosts frequent cartographic exhibitions. There is an archive of 1,000 maps, which are being electronically documented and archived with the help of a special database. Between 1 and 12 November 1999, there was an exhibition of six 19th-century cartoon maps of Europe, five children's maps which had been entered for the international cartographic competition in 1999, and some rare maps drawn by Sotiris Zissis, a self-taught Thessalonian cartographer. Other exhibitions organised by the National Map Library include History in Maps at the Residency, Maps of Ports of Greek Cities of the Twentieth Century in the National Research Institute, and Greek Cartography in Thessaloniki in the Twentieth Century. An educational programme titled The National Map Library Meets Teachers and Children has been drawn up and is addressed to schools in Macedonia and Thrace.

Alaca Imaret Mosque (Turkish: Alaca İmaret Camii) or Ishak Pasha Mosque (Greek: Αλατζά Ιμαρέτ), literally the "colourful mosque", is a 15th-century Ottoman mosque in Thessaloniki, Greece.

The Atatürk Museum (Greek: Μουσείο Ατατούρκ, Mousío Atatúrk, Turkish: Atatürk Evi Müzesi, Atatürk House Museum) is a historic house museum in Thessaloniki, Central Macedonia, Greece.

The Church of Prophet Elijah (Greek: Ναός Προφήτη Ηλία, Naós Profíti Ilía) is a 14th-century church in Thessaloniki, Greece, and a UNESCO World Heritage Site.The church is located in the upper quarter of the old city, and dates to the Palaiologan period, but its original dedication is unknown. In Ottoman times, it was known as the Saraylı Mosque (Palace Mosque or Court Mosque), and through a misinterpretation of this name came about its modern dedication to the Prophet Elijah. It has been traditionally identified as the katholikon of the Nea Moni monastery, built ca. 1360–1370 on the site of a former palace destroyed in 1342 by the Zealot uprising. Modern research, however, has cast doubt on this, since the Nea Moni continued to operate well into the Ottoman period, while the church of Prophet Elijah was converted into a mosque by Badrah Mustafa Pasha immediately after the city's capture in 1430. On the basis of its internal decoration, it has been suggested that the church was the katholikon of the important Akapniou Monastery.Its architectural style, a variant of cross-in-square church known as the "Athonite type", is unique in the city, and was always reserved for katholika of monasteries. The careful masonry, of alternating courses of bricks and white ashlar, is also unusual for Thessaloniki and its region; it is copied from Constantinopolitan architecture. Several of its architectural features have also been interpreted as set to create an ambient atmosphere directly connected with the type of worship, through the way natural light is distributed. Fragments of the church's original decoration survive in the form of wall paintings, fine examples of late Palaiologan art, which influenced later paintings in Serbia.

The Yeni Hamam (Greek: Γενί Χαμάμ, meaning "new hamam" in Turkish) is a building dating to the Ottoman period in Thessaloniki, Greece. It was apparently built in the last quarter of the sixteenth century by Khusref Kenkhuda, a property owner in Thessaloniki who probably served as Kehaya (administrator) for the Vizier Sokolou Mehmet Pasha. It functioned as a double bathhouse with separate compartments for men and women, with the usual layout of rooms. Today it is located at the corner of today's Kassandros and Agios Nikolaos streets.
