Frederick V, Count of Zollern died at which ancestral seat atop Mount Hohenzollern?
Hohenzollern Castle Hohenzollern Castle (German:    ) is the ancestral seat of the imperial House of Hohenzollern. The third of three hilltop castles on the site, it is located atop Mount Hohenzollern, above and south of Hechingen, on the edge of the Swabian Jura of central Baden-Württemberg, Germany.
Holpertal The Holpertal is a valley, just one and a half kilometres long, in the central Palatine Forest of Germany. It lies within the municipality of Ramberg in the county of Südliche Weinstraße in the state of Rhineland-Palatinate. Its V-shaped cross-section was cut by the waters of the Holperbach stream, which has incised deeply into the rock layers of the Lower Bunter. The valley floor climbs from an elevation of about 250 metres to well over 400 metres. Its slopes are covered with mixed forest and sweet chestnut. Whilst at one time, the valley produced raw materials for the traditional broom and brush-making industries, today forestry and tourism predominate.
