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 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.

Vlatades Monastery or Vlatadon Monastery (Greek: Μονή Βλατάδων) is a monastery in Ano Poli, Thessaloniki, Greece. Built in the 14th century during the late era of the Byzantine Empire, it is a UNESCO World Heritage Site along with 14 other Paleochristian and Byzantine monuments of Thessaloniki because of its Byzantine architecture and importance of Thessaloniki during early and medieval Christianity.

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 siege of Thessalonica in 676–678 was an attempt by the local Slavic tribes to capture the Byzantine city of Thessalonica, taking advantage of the preoccupation of the Byzantine Empire with the repulsion of the First Arab Siege of Constantinople. The events of the siege are described in the second book of the Miracles of Saint Demetrius.

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 Casts Museum occupies two rooms in the basement of the new building of the School of Philosophy of the Aristotle University of Thessaloniki, in Central Macedonia, Greece. The museum houses a collection of plaster casts, replicas and original archaeological artifacts. The collection dates from the time of the University's founding and is due to K. Romaio, Professor of Classical Archaeology. The collection of plaster casts of marble and clay originals and replicas of works of art in metal is the finest in Greece. It brings Archaeological Department students into contact with the ancient Greek and Roman art of statue production, as well as ceramics and small-scale art. Room A holds replicas of works from archaic and classical times. Room B exhibits works from Hellenistic and Roman times. Among the most notable works are copies of the Parthenon Frieze, votive reliefs and funerary pillars, statues (youths and maidens), plaques from Athena Niki’s armour, coins, decorative corner roof tiles, funeral urns and masks.
