The church of St. Simon in Valmiera was erected in the 13th century, probably its construction began around 1283. In the fourteenth century, a gothic tower was added from the west. The church suffered during the Livonian War in the second half of the 16th century and during the Polish-Swedish wars at the beginning of the 17th century. Renovation, but also the introduction of baroque elements occurred in the mid-seventeenth century. In 1702, during the Great Northern War, Russian soldiers burned half of the city, including the church of St. Simon. Due to the post-war impoverishment, the temple was not rebuilt for a long time, in addition, its situation was aggravated by further fires, among others in 1738 as a result of a lightning strike. A great renovation was carried out in 1908 to commemorate the 625th anniversary of the building’s existence.
It is not certain whether the temple at the time of creation was already a basilica, or the present appearance obtained only as a result of the fourteenth-fifteenth century reconstruction. It is an orientated, three-nave church with a polygonal ended chancel and a tower from the west.
