The Church of St. Lawrence in Kuusalu is considered to be one of the oldest stone churches in Northern Europe. It may have been built originally by the Gotlandish Cistercian monks of the priory of a Roma monastery locating in Kolga. The church was built probably at the end of the 13th century.
The Baroque-style bell tower was erected in 1760. The Neo-Gothic shape of the church originates from the large renovation made in 1890.
There are many historically valuable artefacts in the church like the pulpit, altar, tower clock, chandelier, candle holders and an embossed brass bracket from the 17th century and Eucharistic vessels made of tin.

Carlsten is a stone fortress built on the orders of King Carl X of Sweden following the Treaty of Roskilde, 1658 to protect the newly acquired province of Bohuslän from hostile attacks. The site of Marstrand was chosen because of its location and its access to an ice free port. Initially a square stone tower was constructed, but by 1680 it was reconstructed and replaced by a round shaped tower. Successive additions to the fortress were carried out, by the inmates sentenced to hard labour, until 1860 when it was reported finished. The fortress was decommissioned as a permanent defense installation in 1882, but remained in military use until the early 1990s.
The fortress was attacked and sieged twice falling into enemy hands. In 1677 it was conquered by Ulrik Frederick Gyldenløve, the Danish military commander in Norway and in 1719 by the Norwegian Vice-Admiral Tordenskjold. At both occasions the fortress was returned to Swedish control through negotiations and treaties.
