Whitewalls
Murosblancos
Whitewalls was the seat of House Butterwell in the riverlands, a fortress raised by the Gods Eye out of stone so white that the local smallfolk nicknamed it the Milkhouse.
All that remains of it now are the ruins that give this place its name on the map, forever tied to a tourney that drew half of Westeros together in the days of King Aerys I.
Chapter 1
The Milkhouse
170 ACBooks only
Lord Butterwell had Whitewalls built around the year 170 after the Conquest, some time after serving as Hand of the King to Aegon IV Targaryen. He chose a site by the Gods Eye and had the stone hauled in from a quarry in the Vale, white as fresh snow.
The floors and pillars were carved from ivory veined with gold, and the roof beams were cut from weirwood trunks. The cost was so outrageous that local smallfolk took to calling the castle the Milkhouse, after the colour of its walls.
Chapter 2
The tourney that ended in dust and salt
Books only
Later, under the reign of Aerys I Targaryen, Whitewalls hosted a great tourney remembered less for the jousting than for what was plotted behind it: the Second Blackfyre Rebellion, hatched in the shadow of the festivities.
The plot failed, and House Butterwell paid for its part in it. Lord Bloodraven ordered the castle torn down stone by stone and the surrounding land sown with salt, so that nothing would grow there again.
Chapter 3
The road that stopped leading there
Books only
Before the War of the Five Kings, reaching Whitewalls meant leaving the Inn at the Crossroads, taking a ferry across the Trident, and following the road on to Lord Harroway's Town. That crossing had been in use for some seventy or eighty years.
In time the river shifted course, and the inn's ferry was left stranded and forgotten, leaving the road to Whitewalls harder to find than it once had been.
