Stanstead is right on the border with Vermont, an American state. The community spills across the two countries and is called Derby Line on the US side. Its most famous sight is a public library purposefully built half on the Canadian side and half on the US side.

The Haskell Free Library and Opera House was built in 1901 as a symbol of friendship between the two countries. A black line on the floor marks where the border is and the library racks and performance stage is in Quebec while the main entrance is in Vermont.

The bi-national historic site serves both communities and residents of the community from both sides of the border are allowed to use it as long as they return to their side of the border when they exit. There is no need to report to customs to visit this building.
Stanstead United Church 
Anglican Christ Church
Apart from an odd public building, Stanstead also has several historic churches. The Stanstead United Church is just behind the library on the Canadian side of the community. This former Congregationalist service began in 1810 and residents from both sides of the border attended the same service even during the War of 1812. The church building was constructed in 1876 and the triangular motifs on the façade represent the Holy Trinity.
After a year of congregating in a local store, the Anglican congregation needed a bigger and more permanent space for services. The Anglican Christ Church was built in 1858 in Neo-Gothic style. Members of the local masonic lodge attended the church and helped to fund the bell tower, which was added in 1908.

The old Rock Island Post Office also doubled as a customs house until 1929. The Department of Inland Revenue collected taxes from local businesses, who had ingenious ways of avoiding them. The building combines American, Quebec Catholic architectural features by using Romanesque Revival for the tower, Second Empire for the roof, and Baroque for the masonry.
Derby Line, VT 
Border crossing
Other attractions include the border crossing itself, the Colby-Curtis Museum, the ornate Stanstead College as well as the Stanstead Stone Circle erected in 2009. The stones were placed right on the 45th parallel, exactly halfway between the North Pole and the equator.
