Ladadika, Historic entertainment district near Port in Thessaloniki, Greece.

Ladadika is a city district in Thessaloniki featuring stone buildings with rectangular windows and paved pedestrian streets. The narrow lanes connect small squares with outdoor seating, lined with dining venues and bars throughout.

Ladadika grew around the port as a wholesale market where olive oil, spices and foodstuffs were traded, and many Jews of Thessaloniki lived there. Before World War I it became the city's red-light district, with brothels and taverns. After the 1917 fire it lost momentum, declined until the 1978 earthquake, and was largely abandoned for about two decades.

Today the neighborhood functions as a social gathering place, with taverns and restaurants filling restored warehouses where merchants once worked. The repurposed spaces show how commercial buildings adapted to become centers for dining and meeting.

The district is bounded by Tsimiski, Salaminos, Kountourioti and Ionos Dragoumi streets, a few minutes on foot from the port and Aristotle Square. Its core covers 6.5 hectares with pedestrian lanes linking Morichovou and Petrakaki squares; allow time to wander, as the layout is compact and maze-like.

The 1985 heritage designation covers 6.5 hectares and 24 building blocks, where about 300 businesses now employ some 1,400 people. The listing followed the area's abandonment after the 1978 earthquake, when regeneration began in the early 1990s. Among the protected structures is the 1896 Natsinas Mansion, one of the few buildings to survive the 1917 fire.
