Blackcrown is the seat of House Bulwer in the southwestern Reach. It is located on the northern shore of Whispering Sound near Oldtown and Three Towers.
Its cliffs are called singing cliffs for the whistle heard from the twisted towers and wind-carved stones standing above the waves.
Blackcrown's maester is Normund.
During his First Voyage, Alyn Velaryon sails past Blackcrown aboard the Lady Baela on his way to to deal with the Red Kraken, Dalton Greyjoy, in the Westerlands.
