The castle in Verona was quite interesting to visit and actually provides one of the best viewpoints of parts of the city from the Ponte Castelvecchio. The structure dates from 1354 - 1355.
By a fluke we noticed some frescoes on a building which the guide book later identified as the frescoes in Case Mazzanti, again dating from the early to mid 16th Century, 1532-1537. Unfortunately they are now somewhat spoilt by the trashy markets held in the adjacent Piazza delle Erbe. These were reminiscent of some of the bad souvenirs we found in Venice, including the obligatory masks, and once again were a tourist Mecca.
