Berkhamsted Castle Guided Tours
Considered the best remaining example of a motte and bailey castle in the UK, Berkhamsted Castle Trust are offering free guided tours of the site which was originally built as a timber structure by William the Conqueror’s half-brother Robert of Mortain. The castle has a rich history which the volunteers will bring to life on the tours on the 14th, 17th, 18th and 20th September, as it has over 950 years of stories. Did you know that it was here that the Anglo-Saxons had surrendered to the aforementioned William, Duke of Normandy in 1066, thus becoming “The Conqueror”?
St Albans Clock Tower
Being the only medieval town belfry in England, the chance to climb the 93 steps of St Albans Clock Tower on the 20th and 21st September is not to be missed! You’ll be given the opportunity to see the city from a new angle, with the Cathedral and wider city spread out below. On the weekend, you can see the working Victorian turret clock up close, admire Gabriel, the medieval bell and the kids can play ‘Hunt the Golden Keys’ for a chance to win chocolate coins!
Ashridge House and the Curse of the Bridgewaters
Discover the secrets of Ashridge House with a very special guided walk, “Ashridge House and the Curse of the Bridgewaters.” Taking place on Friday 12th, Saturday 13th and Saturday 20th September, this Heritage Open Days event uncovers the dark tales and dramatic history of the Bridgewater family. Winding through the woodland paths of the Ashridge Estate, you’ll explore stories of power, scandal and curses in an atmospheric setting that brings history vividly to life. Pre-booking is essential, and the walk includes uneven, sometimes muddy terrain, so don’t forget your walking shoes!
