During the time of King Solomon, around 3000 years ago, Jerusalem include much of what is now the Jewish Quarter, small parts of what is now the Islamic Quarter, and the (currently) extra-mural neighborhood of Silwan. (In fact, most excavations of to discover things about Davidic and Solomonic Jerusalem take place in Silwan to the chagrin of the Palestinian residents living there.)
Same place as today, though it was smaller.
