Church of Saint Margaret of Antioch, Kopčany

It stands in a field to the east of Kopčany and it is about 1.6 km from the major Greater Moravian site at Mikulčice, which is on the other side of the Morava river.

It is approached by a road and is fairly close to the ruins of an 18th-century building, which was used along with former neighbouring lake for catching ducks.

The small church near the Czech-Slovak border has long been considered a baroque chapel and its dating had a stormy development.

[5] The key challenge is to validate if the mortar could be introduced to the older horizon during excavating of the younger graves.

In 2013, a collective of authors analysed a piece of wood from the building by dendrochronology, declaring that it can be dated to 951,[6] which shifts the construction phase to the 2nd part of the 10th century, between the fall of the Great Moravia and the foundation of the Kingdom of Hungary.
