Castle Waterdeep

Castle Waterdeep was a castle located in the city of Waterdeep. Its walls were 60 feet (18 meters) thick on average, and high enough that when banners were displayed in honor of visiting parties, they were visible from many areas of the southern city. They were also enchanted with magic spells. The castle held enough food to feed 50,000 people for ten days, and could accommodate up to 540 prisoners in 90 cells. There were many dungeons beneath the castle, mainly used for storage, which linked through to the Citadel of the Bloody Hand, creating a security concern. There were also deep wells beneath the castle which provided clean drinking water. Most of the castle's passageways were permanently lit by continual light spells.

Militia
The castle was garrisoned by 1,400 of the City Guard, who, along with members of the City Watch, were trained in its courtyard. Seventy warhorses were kept in the castle stables. Thirty guards were always armed and keeping watch on the battlements, while twenty crossbowmen and two wizards were always on duty in a guardroom close to the castle gates.

Capital punishment
The battlements of Castle Waterdeep were used for the hanging of non-nobles.

History
Work began on the castle in 963 DR, outside and to the north of the city walls. It was finished on High Harvestide, 974 DR, the same year Laroun rose to War Lord. As of 1372 DR, it had long since been inside the city walls.
