The Old Church of Västanfjärd was built in 1759-1760. The wooden octagon shaped church was designed by Isak Olin and it’s dedicated to St. Jacob. The belfry was erected in 1763. Interior is mostly from the 19th century.
The newer stone church is located near the old church site. It was built 1910-1912 and represents the Romantic Nationalism style. It was designed by Helge Rancken. The altarpiece (painted by A. F. Ahlstedt) dates back to the year 1864.
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
