We loved our visit to Bellinzone even though we were there in January and on a Monday when they were officially closed. There were no people there and the grounds were open for visiters to explore on their own. It is a very impressive complex of old stone fortifications that are well preserved or restored. I was hoping to find more historical information on this web site since the museum was closed the day we happened upon the castle. The castles and the mountain surroundings are definitely worth a stop.
