York Mansion House is home to all Lord Mayors, living and departed. This spooky season we have a forgotten feud returning to the house and causing havoc amongst the walls. Can you solve the Corpus Codex, a fun book of puzzles for all ages, and uncover the bitter rivals identities so we can demand they leave us in peace? The Corpus Codex is included in the price of general admission, there’s no need to pre-book. York residents get 50% off with proof of address… that’s just £1.75 for a York child!
