Auckland Castle in Bishop Auckland, County Durham, is one of Europe's best-preserved Bishop's palaces, serving as the seat of the Prince Bishops of Durham who governed vast sections of Northeast England with exceptional powers. The site spans nearly 1000 years of history and reopened in 2019 following extensive conservation restoring original wall colors, furniture, and textiles. Key features include St Peter's Chapel, one of Europe's largest private chapels, a Georgian Gothic Throne Room designed by James Wyatt, and the Long Dining Room housing Spanish artist Francisco de Zurbarán's paintings of Jacob and his Twelve Sons since 1756. The palace operates Wednesday-Sunday 10:30am-4:00pm with on-site dining and free Wednesday chapel services.
