The Mail & Custom’s House is rare and historically significant building in Eckerö. It was designed by famous Finnish architects C.L. Engel and C. Bassi and completed in 1828. The purpose of the building was to indicate the power of Russian Empire to seafarers coming from Sweden and it was built intentionally too large for the custom and post office need.
The Mail & Custom's House is well preserved. Today it functions as the post museum and there are temporary exhibitions.
