Thessaloniki

1. 1

   The White Tower

   Thessaloniki’s defining landmark stands on the waterfront promenade where it has anchored the city’s identity since the 15th century. Originally a fortification and later an Ottoman prison, the 34-meter cylindrical tower was whitewashed in 1890 as a symbolic cleansing of its dark history – and the name stuck even after the whitewash faded. Today its six floors house an interactive museum tracing the city’s evolution from Roman Thessalonica through Byzantine splendor to the modern metropolis. The observation deck at the top delivers a 360-degree panorama across the Thermaic Gulf, the Aristotelous Square axis, and Mount Olympus on clear days. The surrounding waterfront park and cafe terraces make the area a natural gathering point, especially at sunset.

   Ano Poli (Upper Town)

   The only neighborhood to survive both the Great Fire of 1917 and modern development, Ano Poli (Upper Town) is Thessaloniki’s atmospheric time capsule. Its labyrinthine cobblestone streets climb the hillside through clusters of timber-framed Ottoman houses, Byzantine churches, and small workshops that preserve craft traditions. The neighborhood encompasses several UNESCO-listed sites including the Monastery of Vlatadon (where Paul the Apostle is said to have preached) and sections of the 4th-century Byzantine Walls that once encircled the entire city. The Eptapyrgio Fortress at the summit – known as Yedi Kule in Turkish – served as an Ottoman and later Greek prison until 1989. Panoramic views from Trigoniou Tower encompass the entire city stretching to the gulf below. Small tavernas here serve some of Thessaloniki’s most authentic home-style cooking at a fraction of waterfront prices.

   Rotunda of Galerius

   Built in 306 AD as a Roman temple to Zeus or Cabeirian deities, this massive cylindrical building later served as a church (featuring magnificent Early Christian mosaics that survive in the dome), then an Ottoman mosque (its minaret still stands as the city’s last remaining one), and now operates as a museum and exhibition space. Its sheer architectural adaptability tells Thessaloniki’s story in a single structure – Roman engineering, Christian faith, Ottoman administration, and modern Greek identity are literally layered into its walls. The building’s 30-meter-diameter dome predates the Pantheon’s concrete construction method and its surviving mosaics (dating to the late 4th century) rank among the earliest examples of Christian monumental art anywhere. The Arch of Galerius stands nearby, its relief panels depicting the emperor’s military campaigns.

   Church of Agios Dimitrios

   The largest church in Greece, this 7th-century basilica honors the city’s patron saint and protector – a Roman soldier martyred here in 306 AD during the Diocletian persecutions. The original 4th-century church was destroyed by fire and rebuilt multiple times, with the current structure dating primarily from the 7th century but incorporating elements from various periods. The underground crypt occupies the site of the Roman baths where Dimitrios was imprisoned and martyred – you can see the remains of the Roman bathhouse below the church floor. Stunning mosaics on the columns and walls date from the 5th to 7th centuries and survived both Ottoman conversion to a mosque (1493-1912) and the Great Fire of 1917. The church operates as an active place of worship and entry is free.

   Archaeological Museum of Thessaloniki

   Macedonia’s foremost museum houses an exceptional collection of artifacts spanning 250,000 years of regional history. The star exhibit is the rich archaeological material from the royal tombs at Vergina and Sindos, including gold wreaths, elaborate jewelry, weapons, and ceremonial objects that illuminate the sophistication of ancient Macedonian culture. Key treasures include the Derveni Krater – a masterwork of ancient Greek metalwork used as a funerary urn – and the Thessaloniki Gold collection documenting the city’s evolution from its founding in 315 BC by King Cassander. The museum’s chronological galleries trace an unbroken arc from prehistoric Macedonia through the Roman period, with particular strength in Hellenistic gold work and numismatics. The building itself, a modernist structure set in gardens near the waterfront, provides a calm setting for a collection that rewards extended exploration.
