Chapter House and Pyx Chamber

Tucked away in the shadow of Westminster Abbey, the Chapter House and Pyx Chamber offer a rare and serene glimpse into the monastic past of London. The Chapter House, constructed in the 1250s, is one of the most stunning examples of Gothic architecture in the UK, famous for its intricate tiled floor and light-filled, octagonal space that once hosted the meetings of monks and, later, the early House of Commons.

Visitors can marvel at the soaring stone vaulting, which remains remarkably intact, as well as the 13th-century wall paintings that provide a vivid window into medieval life. This space was intentionally designed for contemplation and administrative power, and you can still feel the weight of centuries of history lingering in the cool, quiet air of the building.

Next door, the Pyx Chamber, which dates back to the 11th century, serves as a stark, atmospheric contrast to the airiness of the Chapter House. Its thick, austere stone walls and ancient floor tiles have seen it serve as a royal treasury and later a place to store the pyx—the box used to test the nation's coinage. It is an evocative, subterranean vault that feels worlds away from the bustle of modern London.

To make the most of your visit, combine this with a tour of Westminster Abbey, as it is situated within the abbey precincts. It is best to visit on a weekday morning to enjoy the quietude of the space before the crowds of Westminster arrive. Don’t miss the chance to admire the original 13th-century doors, which are among the oldest in the country. It is an essential stop for architecture enthusiasts and those keen to uncover the hidden layers of London's royal and religious history.
