The Royal Crescent ★☆☆

A gorgeous arc of Georgian architecture
This imposing, 500-foot-long semi-circle of terraced homes comprises the nicest set of rowhouses I've ever seen, one of the greatest examples of Georgian architecture in England, built between 1767 and 1775 by John Wood the Younger.
There are 30 houses in all, including No. 16 (now a posh hotel), and No. 1 (now the Museum of Georgian Life—your best chance to see what these originally looked like on the inside).
The sloping grassy lawn in front of it contains a cool ha-ha, a low wall recessed into the landscape so you can't really see it from the houses, but it will still keep grazing sheep on the far side of it.
