The medieval church built in the early 15th century has interesting architectonic details telling about not so peaceful history. Truly medieval looking murals and a number of medieval wooden statues. The apsidal balcony is the only one left in the Nordic countries.

Local History Museum
Historical collections from the surrounding archipelago from handicrafts to fishing gear.
A small museum with an exhibition concentrated on bootlegging! Also some fishing and bird-hunting equipments and boat engines.

Restaurant. Exhibitions and workshops. In the summer children are invited to make marine biological research, studying what they find in the water under the microscope, and are guided on the 18th-century wartime and civil life in Korpo (check the language issues: can trilingual instruction be provided?).
A wooden church built 1932–1934.
Ahvensaaren louhos
An old limestone quarry filled with crystal clear water is a popular destination for scuba divers. The calcareous soil makes some rare plant species to grow on the island. Åvensor has daily ferry connection by M/S Falkö but there are no services for visitors on the island.
