A 900-year-old bishop's fortress in Surrey — Norman keep, medieval palace and five acres of gardens overlooking the town
Built in 1138 by Henri de Blois — grandson of William the Conqueror and Bishop of Winchester — Farnham Castle has served as a fortress, royal residence and bishop's palace for nearly nine centuries. Elizabeth I visited at least six times, and the grounds still feel every inch the seat of medieval power.
The castle divides into two distinct parts: the Norman shell keep, managed by English Heritage and free to enter, and the Bishop's Palace below, where guided tours reveal grand halls, a Tudor kitchen and a chapel that has witnessed eight centuries of worship. Five acres of gardens complete the setting.
Farnham Castle was founded in 1138 by Henri de Blois, Bishop of Winchester and grandson of William the Conqueror, during the turbulent civil war known as the Anarchy. The original tower was a statement of power, but it proved too much for Henry II, who ordered its destruction in 1155. The bishops rebuilt on the same site, raising the shell keep that still crowns the motte today and developing the palace buildings below into a residence that would serve successive bishops of Winchester for over 800 years.
The castle attracted royal attention throughout the medieval period. Elizabeth I was a frequent guest, visiting at least six times between 1568 and 1602. Cardinal Henry Beaufort, who presided over the trial of Joan of Arc, lived here in the early 15th century. By the 17th century, Parliamentarian forces seized the castle during the Civil War, and its military role faded.
The visit naturally splits into two parts. The Norman keep, managed by English Heritage, sits atop a steep motte and is free to enter. The shell walls, buttress turrets and shallow gatehouse date from the late 12th century, and the climb rewards visitors with panoramic views across Farnham and the Surrey hills. A free exhibition near the entrance traces the castle's 900-year history with archaeological finds and photographs.
The Bishop's Palace below is a different experience entirely. Guided tours, available on Wednesday afternoons, lead through the Great Hall with its impressive timber roof, the Tudor brick kitchen, the chapel and a series of rooms that chart the evolution from medieval fortress to ecclesiastical residence. The five acres of gardens surrounding the palace are well maintained, with herbaceous borders, mature trees and lawns that make a pleasant extension to any visit.
Farnham is an easy day trip from London. Direct trains from Waterloo take around an hour, and from Farnham station the castle is a 15-minute uphill walk through the attractive town centre. If driving, the A31 brings you directly to Farnham, with parking available at nearby Farnham Park or in the town's pay-and-display car parks.
The keep is open daily from February to Christmas Eve, but the Bishop's Palace tours run only on Wednesday afternoons from 2pm. If the palace interior is important to you, plan accordingly. Wear sturdy shoes for the motte — the path is steep and can be slippery in wet weather. There is no cafe on site, but Farnham's town centre is a short walk away and has plenty of options for lunch.
The keep and history exhibition are free to enter. Bishop's Palace guided tours cost £5 for adults and are free for under 18s, students and Historic Houses members
The keep is open daily, but guided tours of the Bishop's Palace only run on Wednesday afternoons from 2pm. Plan your visit midweek to see both parts of the castle.
The path up to the Norman keep is steep and uneven, and can be slippery after rain. Flat shoes or trainers are recommended — heels and sandals are not practical here.
The castle overlooks a handsome Georgian high street with independent shops, cafes and pubs. Allow time for a wander and lunch — there is no cafe at the castle itself.
The keep closes between 25 December and 31 January, and winter hours end at dusk if earlier than 5pm. Check the English Heritage website before travelling in the colder months.
Blue badge holders can park at the castle itself, but other visitors should use Farnham Park car park, which is free and within a short walk of the castle entrance.
