Ruhnu at a Glance

About Ruhnu

Ruhnu is a small Estonian island in the Gulf of Riga, administratively part of Saare County, with a single compact village that contains the island’s main services. The island is noted for its historic wooden church and a small lighthouse set among forest and coastal landscapes.

Visitors encounter a quiet village settlement, a 17th-century wooden church with historic fittings, coastal meadows and forest, and simple harbour facilities. The island’s population is small and seasonal, and services for visitors are limited outside the main summer months.

Historically, Ruhnu was home to an ethnic Swedish community for centuries and retains several buildings and burial sites that reflect that heritage. Modern connections are by seasonal ferry and by small aircraft to the island’s airstrip.

Ruhnu sits in the central Gulf of Riga and is reached from the Estonian mainland by scheduled summer ferries and air services; it is managed as part of Saare County.

  • Seasonal access: Ruhnu is sparsely populated and has seasonal ferry and air connections to the Estonian mainland, so travel schedules vary by season.
  • Cultural heritage: The island retains a strong historical Swedish cultural influence and several historic wooden buildings from the 17th and 18th centuries remain intact.

What to See#

  • St. Mary’s Church (Ruhnu Church): St. Mary’s Church (Ruhnu Church) dates from the 17th century and is one of the island’s oldest standing wooden churches, notable for its historic interior fittings.
  • Lighthouse and village: A small 19th-century lighthouse and the compact village provide the island’s primary landmarks and facilities for visitors.
