Turku Art Museum- Discover Nordic artists housed in a beautiful 1900's building. Two artists I discovered that I enjoyed, Carl Larson and John Bauer. Also, a great place to have a beer in front of the museum overlooking the park.
Aboa Vetus & Ars Nova- Housed in a 1920's palace residence, you can explore modern art above and then go below to an underground area of medieval ruins. It's a great experience!
St Henry's Art Chapel- An inspiring building that is a must see.
Niska- Another great restaurant along the river that serves archipelago pizzas and salads. The food was delicious.
Cafe Art- A beautiful cafe by the River Aura for a perfect latte and a pastry. The atmosphere is cozy and artsy with delightful service. A great stop in the morning.
They really know how to repurpose their buildings in Turku: bars!
Uusi-Apteekki- A bar in a former Pharmacy school. This seemed like a locals bar. It was super comfortable and enjoyable to look at all of the old Pharmacy shelves and bottles.
Panimoravintolakoulu- A bar in a Neo-Renaissance school building from 1889 complete with old diagrams and maps on the walls.
Old Bank Bar- A bar built into an old bank that really feels like you are drinking at a bank. They have a large beer selection and I tried a Salmiakki shot (a salty black licorice liqueur) here for the first time. I really liked spending time at this bar, and make sure you walk around and see all of the cool details from the time it was a bank.
Waterloo- A British pub set in an old public bathroom. They play sports and they have British beer. It's a fun place to have a drink.
I would recommend staying at a hotel in the center or near the River Aura, because it's not that easy to get around Turku (mostly walking), and it's nice to be close to the places of interest.There are places you can rent a bike, but during my stay it rained the entire time, so that wasn't a possibility. It's worth looking into if you stay during good weather.
