The Church of Saint Nicholas and the Name of the Virgin Mary in Vilémov is a Roman Catholic church with significant historical and cultural importance. Dedicated to both Saint Nicholas and the Name of the Virgin Mary, it stands on a cemetery at the village's southwestern edge. Since 1963, this architectural gem has been protected as a cultural monument, highlighting its regional heritage value.

The church dates back to the late medieval period, specifically documented in the second half of the 14th century. It underwent significant transformation in 1612 when it was rebuilt or newly constructed in Renaissance style. During this era, Protestantism prevailed in Vilémov, and a Protestant pastor served the community. The suppression of the Bohemian Revolt between 1618 and 1620 led to re-Catholicization across the region. By August 26, 1625, the church was reconsecrated by the dean of Kaaden, marking its return to Catholic hands.

Architecturally, the Church of Saint Nicholas is a single-nave building with an east-oriented polygonal presbytery. Its facade features lisenas and buttresses on the southern side, while an octagonal tower adjoins the northern wall. This tower houses both a sacristy on its ground floor and an oratory above. The interior boasts a barrel vault ceiling and pilasters that divide the nave walls, enhancing its aesthetic appeal. A wooden loft sits above the main entrance on the western side of the nave.

Ownership and administration have changed dramatically over time. In the early 18th century, it belonged to the Račín family from Račín. On September 3, 1711, a fire caused by the then-owner destroyed both the church and the adjacent parsonage. This event led to its reconstruction in Baroque style, largely due to Hraběnka Eleanora Račínová's efforts.

The interior furnishings are predominantly early Baroque, dating back to 1673. The main portal altar features late Gothic sculptures of Madonna, Saint Wenceslas, and Saint Nicholas from the early 16th century, likely crafted by Ulrich Creutz. Two original side altars are dedicated to John the Baptist and Saint Francis. Other Baroque elements include altars devoted to the Crucifixion of Jesus Christ and Saint John Nepomuk, featuring older Baroque sculptures from 1711. The pulpit is richly decorated with original figures of evangelists and four Church Fathers, while Baroque pews are embellished with carved caryatids. Notable items include a stone baptismal font with a Renaissance copper basin from 1598, a Renaissance stone epitaph for Uršula z Doupova, and paintings of Saint John Nepomuk from 1727 and the Annunciation of the Virgin Mary from the early 18th century.

The church's surroundings also hold historical interest. To its south stands a Renaissance cemetery chapel from the latter half of the 16th century. Originally featuring open arcades on its northern side, these were later walled up. Inside was once an epitaph for Vilém z Doupova, created in 1568 by Kaaden master Jörg Mayer, which has since been relocated to a Franciscan monastery in Kaaden due to security concerns. Nearby is a two-story Baroque parsonage with an early 18th-century Pieta sculpture.

Today, the Church of Saint Nicholas and the Name of the Virgin Mary remains a testament to Vilémov's rich religious and architectural history. Its well-preserved structure and historical artifacts make it a worthwhile visit for those interested in exploring the cultural heritage of the Ústecký region. Visitors are invited to experience this remarkable monument, which continues to be an integral part of the community's spiritual life.
