The Church of the Beheading of St. John the Baptist in Krpy is an impressive early Gothic structure located in the northern part of the village, serving as its dominant feature. Built in the 13th century, this church has been protected as a cultural monument since 1987 due to its historical and architectural significance. Originally constructed in the early Gothic style, it underwent Baroque modifications in the 17th century, including the addition of a tower and sacristy. The architecture features a single-nave rectangular structure with an attached square presbytery, characterized by smooth walls and segmental windows.

The church's origins date back to the 13th century when Bohemia was part of the Holy Roman Empire, experiencing significant Gothic architectural development. During this period, religious structures flourished alongside political changes marked by the rise of powerful noble families. By 1384, it was documented as a parish church, indicating its importance within the local community. In the mid-17th century, specifically between 1650 and 1652, it came under the management of the priest from Mšeno, reflecting shifts in ecclesiastical administration.

Architecturally, the Church of the Beheading of St. John the Baptist showcases a blend of early Gothic and Baroque elements. The original structure is characterized by its single-nave rectangular form with an attached square presbytery. Notably, it underwent significant modifications during the 17th century when it was baroquized; these changes included the addition of a tower and sacristy. The exterior features smooth walls supported by buttresses, while the windows are oblong and segmentally arched. The tower is low and smooth, capped with a shingled roof on wooden trusses, above which sits a half-story covered in tin sheeting.

The church's interior reflects its Baroque transformation, particularly evident in its furnishings. A notable feature is the early Baroque altar from the second half of the 17th century, characterized by its columnar design with a segmental pediment and niche. The side panels are adorned with Baroque carvings, though the paintings lack significant artistic value. Additionally, the pulpit, dating back to 1686, is an early Baroque piece featuring segmented columns and framed images of apostles in its recessed areas.

Throughout its history, the church has seen various administrative changes. Initially serving as a parish church by 1384, it later became associated with the Czech Brethren for a brief period before reverting to Catholic administration. In the mid-17th century, the church was managed by a priest from Mšeno, indicating shifts in ecclesiastical oversight.

The church's surroundings also hold historical interest. Opposite the former rectory stands a cross dating back to 1769, shaped like the Stations of the Cross. Additionally, local legend suggests that St. John of Nepomuk celebrated his last Mass here during his return journey from Stará Boleslav, adding an intriguing layer to its history.
