Although these three museums are separate buildings I’m linking them together because you can get an Explorer ticket to visit all three for 20% off the ticket price, which is what I did. As each place takes roughly 30 or so minutes to explore visiting them in one day is a good way of spending a morning, though your ticket does give you 12 months entry to them all. I followed the order recommended on the website but you can of course visit them in any order you want. Therefore I began at The Great Hall, the only remaining part of Winchester Castle which was constructed in 1067 by William the Conqueror.
