This is Os de Balaguer, a small village near Lleida (Catalonia) that has a long history. It originally was an Arab fortification constructed in the 9th century. Some buildings or parts of them still remind the visitor of this period.
The photo is taken from a narrow window of the castle, formerly a loophole, that is a testimony of its eventful history. The big building has been restored for the greater part and you learn all about it on a guided tour.
An interesting part of this tour is the bell ringing crash course, during which you are allowed to ring all the historic bells that together form a small museum. You are even taught to play a short ‘concert’. If you pass this test, you receive a bell ringer’s diploma. I have one!
