The White Tower is the most iconic symbol of the city. The tower was constructed by the Ottomans sometime in the early 15th century and once guarded the eastern end of the city's sea walls. In the 19th century, this tower was used as a notorious prison. Nowadays, it is a welcoming museum of art and local history. The museum offers a rapid lesson in the history of the city. Ideally, you'll take in this well-dosed overview before continuing to the more specialised museums and archaeological sites. For best results, grab the free audio guide at the entrance. The last floor of the tower gives you a wonderful view of the city.

Exploring local markets is an excellent way to discover the city's culture. Foodies will appreciate seasonal fruits and veggies, regional cheeses and street food. Additionally, you can find anything from modern necessities of life to artisanal handmade cosmetics. Kapani Market, the oldest open public market in Thessaloniki, focuses on Greek delicacies, traditional cafes, tavernas and bakeries. Right in the city centre, it sprawls over several pedestrian streets and some parts are covered. Athonos Square, a spot for small traditional shops that offer spices and food products, handmade patio furniture and wicker crafts. Some jewellery, clothing and craft designer shops have sprung up in the last few years. Modiano Market was built in the 1920s and resembles some Parisian markets. Here you'll find traditional food items and a good selection on modern and old-fashioned tavernas. Bezesteni Market, a former Turkish bath from the 15th century now houses clothing, florist and jewellery shops. You can take the stairs to the attic and have a closer look at the six domes. Worth a visit for the architectural value alone. Last but not least, Martiou Market takes place every Saturday at Martiou, a neighbourhood in the eastern part of the city. Fishermen bring fresh catch from the Northern Aegean and from around the Halkidiki region. Fish of all sizes, mussels and octopuses won't stay on the counters long, so come early.

Be sure to snap a selfie with Alexander III of Macedonia on a rearing horse. This is a modern statue of one of the most famous and influential Ancient Greeks mounted on Bucephalus, his famous horse, overlooking the Thermaic Gulf at Thessaloniki. The statue stands by the sea at the YMCA park, very close the White Tower.
