The Church of All Saints in Horsov was built in the Romanesque style at the end of the 14th century and remodeled in the Baroque style in the 17th century. It is one of the most valuable sacral buildings in the West Bohemia region. It is not open to the public. Visits must be arranged with the administration of the State Castle and Chateau in Horsovský Tyn.
It's not so common for a Christian church to be dedicated to the entire heaven of saints (All Saints' Day). Usually, one (or occasionally two) named saints hold the patronage of a church—and thus usually also the patronage of the parish or town in which it is located. The church festival of "All Saints' Day" (in the Catholic Church with the liturgical status of a high feast, in the Protestant Church as a memorial day) has been celebrated on November 1st at least since 835 AD.
Originally a Romanesque church from the 12th century, it was rebuilt in the Gothic style, which it retains today. The last renovation of the church in the Baroque style was carried out in the first half of the 18th century.
