I have always found the Temple insuperably confusing, apart from the tube station.   Where does the Inner Temple become the Middle Temple ?  Who has chambers where and what is their pecking order ?  How much of it is original (not much) and how much postwar reconstruction ?  But now that I have to go back and forth between Blackfriars and Piccadilly several times a week, I am gradually learning my way around.   The bit I like best is King’s Bench Walk which at least looks original, not a neo-Georgian pastiche.   No. 4 is said to be by Wren (do I believe this ?) and was built after the fire of 1677 (no, that is not a misprint):-
