Doors Open Richmond Hill 2024 at the DDO

Join Heritage Services for a tour of our historic observatory and administration buildings.

Doors Open Richmond Hill is an event that supports cultural sites in the community to open their doors to everyone.

This free event is part of Doors Open Ontario, launched in 2002 by the Ontario Heritage Trust.

This year is a reason to celebrate! Richmond Hill is offering Doors Open Richmond Hill for the first time in three years and we are celebrating Richmond Hill’s 150th birthday!

Let’s reunite, reconnect and celebrate all that makes us proud to call Richmond Hill home.
