In the books
In the Song of Ice and Fire novels, the Red Keep is a major castle complex located at the south-eastern corner of the city of King's Landing, directly overlooking the Blackwater Rush and Blackwater Bay. It is built atop Aegon's High Hill, the tallest hill of the city, and affords a panoramic view of the rest of the city. It consists of a number of interconnected buildings, such as the main keep, a secondary castle called Maegor's Holdfast and the Tower of the Hand, the seat of the Hand of the King. White Sword Tower is the base of operations for the Kingsguard. The Red Keep is so-named due to the redstone bricks used to build it.

The Red Keep was built approximately three centuries prior to the events of the series and replaced an earlier wooden fort, built by King Aegon I Targaryen where he first set foot on the continent and used as his base of operations in his conquest of Westeros. The construction of the Keep was an immense undertaking, spanning the reign of the first few Targaryen kings, although modifications and additions to the castle have been made ever since.
