Perhaps the most famous medieval sight near Segovia—and worth a detour between Segovia and Ávila or Valladolid—is the Castillo de Coca, 52 km (32 miles) northwest of the city. Built in the 15th century for Archbishop Alonso de Fonseca I, the castle is a turreted structure of plaster and red brick, surrounded by a deep moat. It looks like a stage set for a fairy tale, and, indeed, it was intended not as a fortress but as a place for the notoriously pleasure-loving archbishop to hold riotous parties. The interior, now occupied by a forestry school, has been modernized, with only fragments of the original decoration preserved.
