Castle of Molinàs Monument · Colera, Alt Empordà, Girona Image of Colera, not of the place itself. The Castell de Molinàs, or de Molinars, a Romanesque work of the 12th-13th centuries, stands in ruins to the west of the hamlet of Colera, in the vall de Molinàs, which is reached by the same forest track that leads up to the church of Sant Miquel de Colera. Rectangular in plan, it preserves two building blocks; the north-facing wall, about ten metres high, has three rows of loopholes and a well-preserved machicolation. Built with slabs of slate bonded with mud, it lacks precise historical records, although it has been linked to the "guàrdia de moros" documented in the 10th century or to a tower mentioned in the consecration records of the monastery of Sant Quirc de Colera from the years 935 and 1123.
