In the shadow of York Minster, right in the heart of the city, Treasurer's House is a unique place to visit. It's a National Trust property, previously owned by Frank Green, an eccentric who created his version of what a historic house should be. He mixed different architectural styles and periods alongside a remarkable collection of antiquities and art to create the house you see today. Visits are by small, organised tours only and there's a new mouse house trail for kids. There's a cafe that's free to enter and a little garden too.
