Main sights
Church of  St. Quirico and Giulitta, one of the oldest religious buildings in the area, mentioned in documents as early as 814. Its Romanesque stone bell tower was built about 1080. 
Parish Church of St. Peter and St. Paul (11th century) and its Romanesque bell tower
Orezia Castle, on a cliff dominating the town. It was built in the late Middle Ages to block the road to Valvarrone Valley. This tower is still in good condition and is flanked by the ruins of ancient dwellings. The first mention of it dates back to 1039 when it sustained a long period of siege by the armies of the Three Larian Parishes. 
Ruins of Castelvedro (5th-6th centuries) located in Mai (400m) on the headland dominating the southern part of Dervio. The fortification is in a commanding position and the ruins of its massive walls are an indication of its significant size. It was part of a defence system created on the shores of Lake Como due to the raids by the barbarians from Rhaetia. 
The Medieval village of Corenno Plinio, positioned around the castle and church on top of the headland.
