Quick Answer: Turku is Finland’s oldest city and former capital (1812 capital transferred to Helsinki), located on the southwest coast 170 km west of Helsinki at the mouth of the Aura River. Population about 200,000. Reach Turku via train from Helsinki (2 hours, €15 to €45 advance). The 12 top experiences cover Turku Castle (1280s medieval), the Cathedral, Aboa Vetus and Ars Nova combined museum, the Aura River summer cafe boats, the Forum Marinum maritime museum, Naantali and Moomin World day-trip, the Luostarinmaki Handicrafts Museum, the Sibelius Museum, and the Turku Art Museum.
Turku is the medieval anchor of Finland. Founded in the 13th century and serving as the country’s capital until 1812 (when Russia transferred the capital to Helsinki to consolidate the new Grand Duchy’s administrative center further east), Turku holds the largest concentration of medieval architecture and historic-Finnish-state institutions in the country. The Turku Castle on the Aura River mouth (built starting 1280) and the Turku Cathedral on the central hill (consecrated 1300) anchor a city character defined by deeper time depth than any other Finnish urban destination.
Beyond the medieval layer, contemporary Turku is the second-most-important Finnish city for design and cultural programming after Helsinki. The Aura River runs through the central city with summer cafe boats (the famous “river boats” that operate as floating restaurants from May through September), strong contemporary art museums, and the broader Turku university scene providing the youthful counterpoint to the medieval institutional weight. The city also serves as the southern gateway to the Archipelago Trail and the Aland Islands ferry routes.
Turku reads as a 2 to 3-day standalone visit or as the base for a 5 to 7-day southwest Finland coastal trip combining the Archipelago Trail, Naantali (with Moomin World), Rauma (UNESCO wooden Old Town), and Hanko. The 2-hour train from Helsinki keeps the city accessible for travelers extending beyond the capital; the ferry connections to Stockholm and Mariehamn make Turku the natural multi-country trip hub for the broader Scandinavia exploration.

12 Top Things to Do in Turku
The 12 things to do below cover the realistic 2 to 4-day Turku visit with medieval heritage, contemporary art, and the Aura River summer scene as the three primary threads.
1. Turku Castle (Built 1280s)
Turku Castle (Turun linna) is one of the oldest and largest surviving medieval castles in the Nordic countries. Construction began in the 1280s and continued through the 1500s; the structure served as the administrative center of Swedish rule over Finland for centuries. Entry €13 adult; closed Mondays in winter. Allow 2 to 3 hours. The castle includes the original medieval rooms, restored Renaissance halls, the castle church, the historical museum, and the dungeon area. Reach the castle via local bus 1 from the central market square (10 minutes, €4) or a 30-minute walk along the Aura River. The castle sits at the river mouth near the modern Turku passenger harbor.

2. Turku Cathedral (Consecrated 1300)
Turku Cathedral (Turun tuomiokirkko) is the mother church of the Finnish Evangelical Lutheran Church and the oldest medieval cathedral in Finland. Consecrated in 1300, the cathedral has undergone multiple rebuildings after fires (most significantly after the Great Fire of Turku in 1827) but retains the original medieval stone walls and the central altar area.

The small adjacent cathedral museum (€2 extra) covers the church history and houses preserved medieval ecclesiastical artifacts.

3. Aboa Vetus and Ars Nova Combined Museum
Aboa Vetus and Ars Nova (Old Turku and New Art) is the combined archaeology-and-contemporary-art museum on the Aura River.

4. Aura River Cafe Boats (Summer Only)
The Aura River cafe boats (joelaivat) are the iconic Turku summer experience: 8 to 10 historic and contemporary boats moored along the central Aura River operate as restaurants and bars from early May through late September. The boats include Wienerwald, S/S Bore (a restored 1960 passenger ship), and several smaller cafe-boat operations. Pricing varies: cafe coffee and pastry €6 to €12, mains €18 to €35, cocktails €10 to €15. No reservations needed for cafe-boat seating during summer weekday afternoons; book ahead for July weekend evenings. The boats provide the strongest single Turku-summer atmosphere and pair naturally with the riverside walking tour.

5. Forum Marinum Maritime Museum
Forum Marinum is the Finnish national maritime museum located at the Turku harbor 2 km southwest of the central city. The museum holds 5 historic ships moored as floating exhibits including the 1902 sailing barque Sigyn (open for boarding), the WWII-era Karjala submarine, and the modern Keihässalmi minelayer.

7. Luostarinmäki Handicrafts Museum
Luostarinmäki Handicrafts Museum (Luostarinmäen käsityöläismuseo) is the only surviving block of pre-Great-Fire-of-1827 Turku architecture, preserved as an open-air museum of 18 historic wooden buildings on a small hill in central Turku.

Rental cars from Turku Airport or central station are the standard travel method; bicycle is the athletic alternative. The trail is best driven mid-May through mid-September when all seasonal ferries operate. Travelers can also do a shorter 2-day Pargas-and-Nauvo version as a Turku day-trip block.

Both ferries depart from the Turku passenger harbor near the castle. Book 2 to 4 months ahead for July departures.

Frequently Asked Questions
Why is Turku Finland’s oldest city?
Turku was founded in the 13th century as a Swedish trading post and cathedral seat, and served as Finland’s capital from the medieval period until 1812 when Russia transferred the capital to Helsinki. The Turku Castle (1280s) and the Turku Cathedral (1300) are the two oldest surviving monumental buildings in Finland. The city holds the deepest medieval-historical layer of any Finnish urban destination.
How do I get to Turku from Helsinki?
Train via VR Group takes 2 hours with departures every 30 to 60 minutes at €15 to €45 advance booking. The Pendolino high-speed trains complete the route in 1 hour 50 minutes. Bus runs 2.5 hours at €10 to €25. By rental car, the drive is 2 hours via Highway 1.
How many days do I need in Turku?
2 to 3 days for the standard visit covering Turku Castle, Cathedral, Aboa Vetus, Aura River cafe boats, and Forum Marinum. 4 days adds the Naantali day-trip plus the Luostarinmäki, Sibelius, and Turku Art museums. 5 to 7 days for travelers extending with the Archipelago Trail or Aland Islands ferry.
When is the best time to visit Turku?
Late May through August for the open Aura River cafe boats, the Luostarinmäki living-history demonstrations, and the warm-weather harbor scene. Year-round for the cathedral, castle, and indoor museums. September catches autumn color with quieter conditions and 25 to 35 percent off summer hotel rates.
Should I stay in Turku or day-trip from Helsinki?
Stay 2 to 3 nights. The 2-hour Helsinki-Turku train allows a day-trip but the visit feels rushed; the medieval cathedral and castle alone justify a full day each. The Aura River cafe boat scene also rewards an overnight stay with evening dining and the late-summer twilight atmosphere that day-trippers miss.
Can I take a ferry from Turku to Sweden?
Yes. The Turku to Stockholm ferry (Viking Line and Tallink Silja) runs overnight at 10 hours and €90 to €230 per person including cabin. Multiple daily departures. The same ferry route can be combined with the Aland Islands day-stop. Book 2 to 4 months ahead for July departures.
Key Takeaways
- Turku is Finland’s oldest city and former capital (until 1812); population 200,000; 2 hours by Pendolino train from Helsinki.

Final Thoughts
Turku is Finland’s medieval anchor and the natural second-or-third city after Helsinki on most Finland trips. The 2-hour Pendolino train combined with the strongest concentration of medieval architecture in the country, the Aura River summer scene, and the ferry connections to Sweden and Aland deliver a meaningfully different Finnish urban experience. Build the visit around 2 to 3 days; extend with Naantali, the Archipelago Trail, or the Aland Islands for the broader southwest Finland coastal trip.
