The inhabitants on Hasslö did not get a church of their own until 1890. Before, they had to go over the sea to Förkärla for whatever reason they had to visit their church. In the winter it must have been troublesome some time, for example when they had to transport coffins over ices that neither held nor burst.
The church is built of brick from Nättraby and it is built in neo-Gothic style. The sanctuary is placed in the north. The pulpit, decorated with roses, is placed to the left of the sanctuary. The ceiling is made of wood and arched.
