King's Landing is the capital city of Westeros. Loacted on the east coast of Westeros, overlooking, Blackwater Bay, it is where the Red Keep, the seat of the King, and the Iron Throne can be found. A bustling, dirty city, it is a place of danger and intrigue, where assassins can be hired discreetly, and you cannot turn a corner without being in the presence of one of Lord Varys' or Lord Baelish's spies.
The Great Sept of Baelor can also be found here, where the High Septon of the Faith of the Seven can be found. No temples dedicated to other gods can be found here in such grandness and splendour, although some people within the city to worship the Old Gods, or R'hollor.
