Middlesex County Court House

Middlesex County Court House is a courthouse in London, Ontario, built between 1827 and 1829 from locally quarried stone with a central tower, corner octagons, and pointed-arch windows. It occupies 4 acres of land between Dundas Street and King Street in downtown, where its distinctive architectural features shape the urban landscape.

The building was constructed after Lieutenant-Governor John Graves Simcoe had initially considered this location as a potential provincial capital before Toronto was selected for Ontario's government. This early focus shows the place's importance in Ontario's settlement story.

The courthouse displays Gothic Revival details with exposed timber ceilings in the courtroom and distinctive crenellations that reflect how early Canadian institutions were built. These design choices shaped how such public spaces looked and felt in the 19th century.

The courthouse sits on a large property in downtown between two main streets, making it easy to find and approach. Plan to visit on weekdays when the building functions as an active court, and check whether tours are possible outside regular business hours.

The building gained protection through three separate designations: National Historic Site status, Ontario Heritage Trust easement, and municipal heritage recognition. This triple acknowledgment shows how it is viewed as important across different levels.
