The old Cistercian monastery of Melón contains in its church one of the largest and most imposing sanctuaries in Galician monastic architecture. It was founded by monks from Clairvaux Abbey in France, in 1142. It was once very powerful, as attested by the remaining architecture.
Various rooms in the monastery, the galleries in the cloister and the two later chapels are currently undergoing restoration, as well as the entrance to the monastic site.
The only element remaining from the primitive Romanesque church with three naves is one section of a nave, the transepts with two semicircular chapels, and an interesting ambulatory with freestanding columns. Its walls and roofs were refurbished once again in the late 19th century in the historicist style. It is topped with cross and quarter-sphere vaults, and has a rectangular tower at the point where the transept meets the naves.

From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
