Tower of Sant Joan Monument · Osor, Selva, Girona The Torre de Sant Joan stands at the end of a buttress on the left bank of the riera d'Osor, about two kilometres from the village, in a narrow pass that controlled and defended the only access to the town from the east; it may have served as a watchtower and might be the so-called torre dels Recs, documented since 1310. It is a square building of 6.28 by 6.28 metres, with walls 1.10 metres thick and a surviving height of about 8 or 9 metres; it had three floors, of which the ground floor is best preserved, with an entrance door 125 centimetres wide and arrow slits on each façade. By its building technique it is considered a work of the late Romanesque, from between the 12th and 13th centuries. It is declared bien cultural de interés nacional (the highest level of heritage protection in Catalonia). Photo: Joan Cantal Coll (CC BY-SA 4.0) What to see and do in Osor
