I don't like Mondays

I went to Possagno on a Monday, and it was shut. The next time I went, not on a Monday, I saw a note on the door of the Tempio Canoviano that gave the opening times. Half an hour after the doors should have opened I went to the Canova Museum (not a short walk) to ask why the Tempio was not open. The attendant told me that the times posted were the winter times, but they had not yet come into effect. You can find out all you need to know on-line, so I will say no more, other than don't believe the discovertreviso.com site that says the Tempio is open on Mondays.
