The many small turrets might appear to be haphazard, but they provide excellent fields of fire. Similarly, the tall, slender towers hold watchposts that can be defended by one man against an army and command much of the area around. The many courtyard gardens can be sealed and turned into killing rooms to dispose of invaders. The Hall of Minstrels in Brionne is the most important centre for those entertainers in the world. It stands on a small prominence in the southern quarter of the city, and is surrounded by a garden. The building itself is circular, built of white stone, and home to an auditorium with flawless acoustics. Minstrels can be found performing there at any time of the day or night.[1a]
