The mystery church of Cérvoles

Tucked away in the hills of Senterada, Spain, you'll find the mystery church of Cérvoles. A 12th-century ruin, but altered in the 18th century, this church is a question that no one can answer. The church, originally dedicated to Santa Maria or Santa Eulàlia, is a protected Bé Cultural d'Interès Local. At first glance, it appears to be a single-naved church with a semicircular apse and a square bell tower at the northeast corner. However, only parts of the original walls of the apse and the two side walls can be identified in the external walls. Despite the lack of evidence, the construction of the church can be dated to the end of the 12th century based on the type of appearance and the regular and well-cut stones.
