Hidden Minster Tours

Scroll to explore

Unlock the secrets and mysteries of York Minster with a Hidden Minster tour as part of York Unlocked’s ‘open buildings’ weekend.

Chapter House Roof and Mason’s Loft

Go above the rooftops of York and explore one of York Minster’s architectural gems with our hidden tour of the Chapter House roof and old Mason’s Loft.

Learn how 13th century Masons used a revolutionary engineering technique to create a structure that is one of the wonders of medieval carpentry. View the centuries-old design drawings still visible on the Tracing floor, see Victorian wooden templates and touch timber believed to be nearly 1,000 years old.

Crypt Passages

Delve behind the walls of the present-day Crypt, where your expert guide will reveal the foundations of three spectacular cathedrals, built on this site over nearly 1,000 years.


The tours will run at 10.00am, 11.30am, 1.30pm and 3.00pm on Saturday 15 October. Tickets are free but spaces are limited, pre-booking is required. Tickets include one-off entry into York Minster.

Tickets will be available in early October via York Unlocked’s website.

York Unlocked is based on the successful models created by Open Doors & Open House in the UK and across Europe 30 years ago. It has been created to raise public awareness and appreciation of architecture and the built environment of York. They are joining over 100 cities around the world that celebrate their urban landscape. More information about the event is available here.
