Monastir Synagogue (Thessaloniki)

The Battle of Thessalonica was fought in the summer or autumn of 380 by Fritigern's Goths and a Roman army led by Theodosius I. Reconstituted after Adrianople, the East Roman army suffered another major defeat. Theodosius retreated to Thessalonica and surrendered control of operations to the Western Emperor, Gratian.

Hamza Bey Mosque (Greek: Αλκαζάρ Θεσσαλονίκης) is a 15th-century Ottoman Mosque in Thessaloniki, Greece. Modern Thessalonians commonly known it as Alkazar, after a cinema that operated in the premises for decades.

Thessaloniki Province was one of the two provinces of Thessaloniki Prefecture of Greece. Its territory corresponded with that of the current municipalities Ampelokipoi-Menemeni, Chalkidona, Delta, Kalamaria, Kordelio-Evosmos, Neapoli-Sykies, Oraiokastro, Pavlos Melas, Pylaia-Chortiatis, Thermaikos, Thermi and Thessaloniki. It was abolished in 2006.

Venizelou (Greek: Βενιζέλου, literally Venizelos [Street]) is an under-construction metro station serving Thessaloniki Metro's Line 1 and Line 2. The station is named after Eleftherios Venizelos, Liberal Prime Minister of Greece. It is expected to enter service in 2023. Construction of this station has been held back by major archaeological finds, and it is designated as a high-importance archaeological site by Attiko Metro, the company overseeing its construction. At this station, Roman Thessaloniki's marble-clad and column-lined Decumanus Maximus (main east-west avenue), along with shops and houses, was found running along the route of the Via Egnatia (modern Egnatia Street) at 5.4 metres (18 ft) below ground level.The discovery was so major that it delayed the entire Metro project for years. A historian dubbed the discovery "the Byzantine Pompeii". Attiko Metro wanted to disassemble the road and re-assemble it elsewhere, while the City Council wanted Attiko Metro to redesign its network to accommodate the discovery in situ. Ultimately the case reached Greece's Council of State and Attiko Metro re-designed the metro line, sinking the tunnels to a depth ranging from 14 metres (46 ft) to 31 metres (102 ft), and making provisions for mini museums within the metro stations, similar to those of Athens Metro stations like Syntagma, which houses the Syntagma Metro Station Archaeological Collection.Venizelou station will also feature an open archaeological site, the first of its kind anywhere in a metro station, in order to maintain the road in its original location. At the next station, Aghia Sofia, where the same road was unearthed (and where it is arguably more important, as a public square was found as well), the road will be disassembled and reassembled elsewhere.Venizelou station also appears in the 1988 Thessaloniki Metro proposal under the name Alkazar. Alkazar is the popular name for Hamza Bey Mosque, a landmark on Egnatia and Venizelou streets.

The Konak (Turkish: Konak, Greek: Κονάκι; also known as the Government House (Διοικητήριο)) is an Ottoman-era building in central Thessaloniki, Greece. Originally built in 1891 as the residence (konak) of the governor-general (vali) of the Salonica Vilayet and the seat of the Ottoman authorities, it now houses the Ministry of Macedonia and Thrace.

The Bedesten of Thessaloniki (Greek: Μπεζεστένι Θεσσαλονίκης) is a historical Ottoman market in the city of Thessaloniki, Greece, built during the reign of Sultan Mehmed II (in around 1455–1459). It is located on Venizelou and Solomou streets, near the Hamza Bey Mosque and the city's old town hall. A bedesten is a type of Ottoman old market, and is derived from the Arabic word bez meaning fabric.

The Church of Panagia Chalkeon (Greek: Παναγία τῶν Χαλκέων) is an 11th-century Byzantine church in the northern Greek city of Thessaloniki. The church's well-preserved Byzantine architecture and testimony to the importance of Thessaloniki in early and medieval Christianity led it to be inscribed on the UNESCO World Heritage List in 1988 along with other Paleochristian and Byzantine monuments of Thessaloniki.

The siege of Thessalonica between 1422 and 1430 saw the Ottoman Empire, under Sultan Murad II, capture the city of Thessalonica. Afterwards, the city would remain in Ottoman hands for the next five centuries until it became part of the Kingdom of Greece in 1912. Thessalonica had already been under Ottoman control from 1387 to 1403 before returning to Byzantine rule in the aftermath of the Battle of Ankara. In 1422, after the Byzantines supported Mustafa Çelebi as a rival pretender against him, Murad attacked Thessalonica. Unable to provide manpower or resources for the city's defence, its ruler, Andronikos Palaiologos, handed it over to the Republic of Venice in September 1423. The Venetians attempted to persuade the Sultan to recognise their possession, but failed as Murad considered the city his by right and the Venetians to be interlopers. This impasse led to an Ottoman blockade of Thessalonica, which occasionally flared up with direct attacks on the city. At the same time, the conflict was mostly fought as a series of raids by both sides against the other's territories in the Balkans and the Aegean Islands. The Venetians repeatedly tried to apply pressure by blocking the passage of the Dardanelles at Gallipoli, with little success. The blockade quickly reduced the inhabitants to near starvation, and led many to flee the city. The restrictions placed on them by the siege, the inability of Venice to properly supply and guard the city, the violations of their customary rights, and rampant profiteering by Venetian officials led to the formation of a pro-surrender party within the city, which gained strength among the inhabitants. The city's metropolitan bishop, Symeon, encouraged his flock to resist. However, by 1426, with Venice's inability to secure peace on its own terms evident, a majority of the local population had come to prefer a surrender to avoid the pillage that would accompany a forcible conquest. Venice's efforts to find allies against the Ottomans also failed: the other regional potentates either pursued their own course, were themselves antagonistic to the Venetians, or were defeated by the Ottomans. After years of inconclusive exchanges, the two sides prepared for a final confrontation in 1429. In March, Venice formally declared war on the Ottomans, but even then the conservative mercantile aristocracy running the Republic were uninterested in raising an army sufficient to protect Thessalonica, let alone to force the Sultan to seek terms. In early 1430, Murad was able to concentrate his forces against Thessalonica, taking it by storm on 29 March 1430. The privations of the siege and the subsequent sack reduced the city to a shadow of its former self, from perhaps as many as 40,000 inhabitants to c. 2,000, and necessitated large-scale resettlement in the following years. Venice concluded a peace treaty with the Sultan in July, recognising the new status quo. Over the next few decades, the antagonism between Venice and the Ottomans morphed into a rivalry over control of Albania.

The Apostolic Vicariate of Thessaloniki (Latin: Vicariatus Apostolicus Thessalonicensis) is a Latin Church ecclesiastical territory or apostolic vicariate of the Catholic Church in northern continental Greece. It is exempt to the Holy See and is not part of any ecclesiastical province, and remains vacant under apostolic administrators since its only proper apostolic vicar, Alessandro Guidati, was promoted Archbishop of Naxos, Andros, Tinos and Mykonos in 1929. Its cathedra is within the Cathedral of the Immaculate Conception, in Thessaloniki.

The Church of Saint Catherine (Greek: Αγία Αικατερίνη) is a late Byzantine church in the northwestern corner of the Ano Poli, Thessaloniki, Greece.

The Immaculate Conception Cathedral (Greek: Καθεδρικός Ναός της Αμιάντου Συλλήψεως της Θεοτόκου) is a Roman Catholic church located on Frangon street in the city of Thessaloniki, in northern Greece. The church follows the Roman or Latin rite and functions as the seat of the Apostolic Vicariate of Thessaloniki (Vicariatus Apostolicus Thessalonicensis or Αποστολικό Βικαριάτο Θεσσαλονίκης).

The Roman Forum of Thessaloniki is the ancient Roman-era forum of the city, located at the upper side of Aristotelous Square. It is a large two-terraced forum featuring two-storey stoas, dug up by accident in the 1960s. The forum complex also boasts two Roman baths, one of which has been excavated while the other is buried underneath the city, and a small theater which was also used for gladiatorial games. Although the initial complex was not built in Roman times, it was largely refurbished in the 2nd century. It is believed that the forum and the theater continued to be used until at least the 6th century.The area of the forum was planned to be the site of the Thessaloniki Municipal Courthouse (in Greek: Δικαστικό Μέγαρο), but after the ruins were discovered during the excavation, the project was scrapped. While the courthouse building was relocated, the intended name of the square ("Courthouse/Dikastirion Square") still survives in popular use. The official name of the square however is "of Ancient Agora (Archaias Agoras)".
