Review for Allman Park Review For Big ZZ Princess Slot Hall Google User Feb 20 '18 at 20:13 A significant and historical royal castle (the oldest castle in the world in fact) Lots of things to look at and explore so factor in a couple of hours at least to take it all in! The entrance price is a little steep but it is worth the visit! Expect lots of tourists and maybe even a royal visitor :-) Windsor town itself is a good place to explore so you can certainly make a day here View full site to comment or like
