Winterfell

From A Wiki of Ice and Fire

Winterfell is a castle in the North of Westeros. It is the ancestral home and seat of power of House Stark, which has ruled the North for millenia. It lies on the Kingsroad that runs from King's Landing to the Wall. Built on top of a hot spring, it uses the water from that spring for heating, making it more comfortable than other castles during the harsh northern winter. Under the castle there is a crypt where the Starks bury their dead. There is a 'winter town' outside which is apparently mostly deserted during summers, but where the smallfolk gather in winters.

The castle was sacked and burned down by Ramsay Snow. The crypts remain intact.
