The rotunda was built in the second half of the 13th century, probably in the 1240s. It is believed that along with the smaller rotunda in nearby Prihradzany and the non-existent castle under the hill Muteň, it created a defense system, in addition to its original sacred function. In addition to location and visual contact of all three, the narrow windows of the building also show defensive function. Around 1270, the interior of the rotunda was decorated with romanesque frescoes. The pressure of the roof on the vault led to the first renovation in the first half of the 14th century. During it, a stone lantern was demolished on the roof of the building. In 1750, next to the rotunda, a baroque belfry was built. Artistic, architectural and archaeological research took place in the 70’s and 80’s of the last century. In 2007, the renovation started, thanks to the support of the Ministry of Culture of the Slovak Republic.
The building is a round rotunda with a diameter of 1110 cm. The diameter of the internal apse is 780 cm and probably is the largest building of its kind in Central Europe. The original height of the circuit walls is not known as a result of subsequent interventions. The facade of the building is decorated with lesenes, which form the motifs of blind arcades around the perimeter of the rotunda. Inside the nave there are remains of the matroneum. It was supported by pillars with a circular cross-section and ending with stone heads. The interior was originally decorated with romanesque mural polychrome.
