Overlooking the village of Portland and Big Rideau Lake is the Emmanuel Heritage Centre (1861), a former Anglican church. Its beauty lies in its simplicity — constructed in the Gothic revival style with sandstone quarried onsite, featuring unusual stone buttresses. Owned by the Portland on the Rideau Historical Society, the impressive interior hosts Portland historical memorabilia, musical events and seasonal markets.

Discover one of only four blockhouses built on the Rideau Canal. This building features thick walls designed to withstand small cannon fire and a tin sheathed roof to defy torching. Situated on a knoll to observe the lock and channel, the blockhouse can hold a 20-man garrison and house the lockmaster. Come and enjoy this rare opportunity to peek inside! (Photo: Rosanne Lake)
