Adlerfelt — Natural Wine Deep Cut

Adlerfelt is a natural wine restaurant inside a 250-year-old fortress building on Suomenlinna — the UNESCO World Heritage island 15 minutes by ferry from Helsinki's Market Square. Opened in 2020, with 30%+ natural wines on the list and seasonal Nordic cuisine that uses the island setting as both ingredient source and atmosphere. They also run Adler Wine House, a dedicated summer wine bar on the fortress grounds. The deepest wine cut on Suomenlinna — most visitors miss it entirely. Ferry from Kauppatori, then a 10-minute walk across the island.

What to do there

4 things to do

1. 1 Cross the Water on a €3.30 Ticket to a UNESCO Fortress Adventure · Free

   Where: Market Square (Kauppatori) ferry pier — the side facing the Presidential Palace and Allas Sea Pool. Buy your HSL ticket BEFORE you board (machines on the pier, or the HSL app). Zone A ticket, €3.30.

   What: This is the cheapest direct connection from a capital city's central market square to a UNESCO World Heritage Site on the planet. The ride takes 15 minutes. In winter, there's a non-trivial chance the ferry will break ice on the way. In summer, you'll pass pleasure boats and see the fortress silhouette growing larger against the Baltic. Suomenlinna was built starting in 1748 as the largest construction project in all of 18th-century Sweden — they called it the Gibraltar of the North. It surrendered to Russia after a two-month siege in 1808 anyway. You're arriving at a place that's held three countries' flags.

   How: Ferries run daily 6am–2:20am. Summer (May–September): every 20–30 minutes. Winter: every 40–60 minutes. The crossing is exactly 15 minutes. When you step off at the main pier on Iso Mustasaari island, Adlerfelt restaurant (B 1) is a 5-minute walk — it's one of the first grand buildings you'll see, entrance at near-ground level.

   Backup: If the HSL ferry is delayed, the summer water bus (late May–September) also serves the island, stopping at Artillery Bay near King's Gate. Same price zone.

2. 2 Find the Man Who Waited 11 Years to Be Buried Here History · Free

   Where: Walk south along the Blue Route (marked with blue signs from the ferry pier). Cross the bridge from Iso Mustasaari to Susisaari island. The Great Courtyard (Linnanpiha) is in the centre of the fortress — the largest open square you'll find. The tomb sits in the middle of it.

   What: The man in this tomb, Admiral Augustin Ehrensvärd, spent his entire adult life building this fortress. He died 4 October 1772, having watched it grow from bare islands into the most formidable naval base in the Baltic. King Gustaf III of Sweden decreed he should be buried right here, in the courtyard Ehrensvärd designed himself. But the tomb took 11 years to build. For those 11 years, Ehrensvärd's body lay in a temporary grave in a Helsinki church. When his coffin finally arrived on 5 July 1783, the king himself came to Suomenlinna for the ceremony. The monument you're looking at? Gustaf III sketched the design personally. It still wasn't completed until 1805 — 33 years after Ehrensvärd died.

   How: The Blue Route from the main pier to the Great Courtyard takes about 15–20 minutes on foot. Follow blue markers and the route maps posted throughout the island. The tomb is free to view at any time — it's an open courtyard. Stand at the tomb and look at the 1760s baroque buildings surrounding you: this was the administrative capital of the entire Swedish Baltic defence.

   Backup: If you'd rather have context first, the Ehrensvärd Museum (inside the Commander's House at the Great Courtyard, open May–September) gives you his life story in full before you reach the tomb. Admission included with guided tour ticket.

3. 3 Taste the Wine List That Beat All of Helsinki's Fine Dining Wine · Price: moderate

   Where: Restaurant Adlerfelt, Suomenlinna B 1 — the 250-year-old stone building a 5-minute walk from the ferry pier, on Iso Mustasaari island. Open Tuesday–Saturday 12:00–20:00. Closed Sunday and Monday. Book ahead: +358 41 317 0998, or reserve online. Walk-ins are accepted (they hold capacity) but this place fills.

   What: In 2024, Adlerfelt — which you just reached by a €3.30 ferry — won both 'Best Short List of the Year Finland' AND 'Sustainable Wine List of the Year Finland' from Star Wine List, beating Helsinki's top city-centre restaurants. Their secret: a minimum 30% natural wine commitment (a formal Raisin certification threshold), with organic and biodynamic European family producers filling the rest. The list is short by design — fewer than 200 bottles — because head chef Niko Suomalainen's menu changes multiple times a year and every wine has to actually work with whatever's seasonal. Ask the staff which natural wines they're currently excited about. They will have an answer.

   How: Order by the glass to taste across the list, or ask for a pairing recommendation for whatever Niko's team is running today. Look for any Baltic Sea fish dish — the pike perch preparations in particular have drawn consistent praise from reviewers. The bread is exceptional: don't ignore it. Tell them you're interested in the natural wine side of the list specifically; the staff actively curate and want to talk about it.

   Backup: If the restaurant is full, the Adler Wine House (yellow building directly behind, open late May–early September) serves the same organic/biodynamic European wine selection in an outdoor fortress setting. Different format, same sourcing philosophy.

4. 4 Drink Biodynamic Wine Where a Cannon Once Aimed at Russia Wine · Price: low · Optional

   Where: Adler Wine House — the yellow building directly behind the main Adlerfelt restaurant, Suomenlinna B 1. Open late May through early September.

   What: The summer wine bar is outdoors on the fortress grounds. You're drinking organic, biodynamic European wines a few hundred metres from 18th-century Swedish cannons that once pointed east across the Baltic toward Russia. The fortress was built specifically to stop the Russian empire from advancing west. Russia took it anyway, in 1808, after two months. Now it's a UNESCO World Heritage Site full of Finnish families having picnics and people like you with a glass of natural wine from a small European family producer. Domestic Finnish beers are also on the list.

   How: No reservation needed for the Wine House — it's walk-in only, outdoor format. Arrive in the afternoon for the best fortress light. Order a glass, find a spot on the grass or stone, and stay. The snack menu is simple but designed to pair with the wines. This is where Helsinki locals actually come on summer weekend afternoons — not the tourists who've ticked the main pier and left.

   Backup: If the Wine House is closed (outside summer season or bad weather), the main Adlerfelt restaurant interior is the correct alternative — same sourcing philosophy, year-round.
