The Brome County Historical Society, founded in 1897, owns and operates a Museum and Archives centre and comprises seven buildings across two campuses. The Museum and Archives centre house treasures that recall the village’s foundation by the Loyalists, agricultural and commercial history and military artefacts including a rare First World War Fokker D.VII plane. The main Centennial Building, the Archives centre and the ever-popular Marion L. Phelps Building housing the Children’s Museum are open year-round, Monday through Saturday, and the entire campus is open Monday through Sunday, from Victoria Day weekend through Thanksgiving.

The first St. Paul’s Anglican Church was built primarily of wood in 1842 at the request of the early English settlers of Brome County. In 1892, a second St. Paul’s Church was constructed, primarily of brick, in order to accommodate the increasing number of members of the congregation. Finally, in 1941, a third, Gothic-style, St. Paul’s Church was built by architect C.L. Douglas after a fire destroyed the previous structure. Particularly interesting are the old stained-glass windows that recall the village’s American forefathers and the historic Casavant organ.

This general store was built in 1856 by Luke Knowlton. The Brouillette family subsequently operated the store from 1919 until 1994. Interestingly, the interior tin ceiling is still the original.

Once a Masonic Lodge, this attractive fieldstone building was constructed in 1852. It was originally the home of Israel England, a Vermont-born businessman, who came from Dunham to settle in Knowlton in 1840 at the age of 20. England went into the tanning industry on land he purchased from Paul Holland Knowlton.

Originally built in 1843, this building served as a tannery owned and constructed by Israel England. In 1903, a fire destroyed the building leaving only the stone foundation. It was subsequently rebuilt and was used as a club house called the Dug Out and later became a successful business under the name Crandall Auto Body. In 2009, the building was restored and became the Star Café known today.

The Pettes Memorial Library was the first free rural public library in the province of Québec. The Library was built in 1893 and officially opened in 1894 by Narcissa Pettes in memory of her husband Nathaniel Pettes (Federal M.P., 1874–1878). Many of the books in the early library collection were donated by local residents of Knowlton as many of them were very well-to-do and had private libraries in their homes.

Built in 1849 and known as Blinn’s Inn, the building was the original stagecoach stop of the Old Magog Road Stage Coach Line going through Bolton Pass and the village’s first public establishment with accommodations, food and beverages. In the early 1900s, the Inn was purchased and renovated by James M. Robinson of North Sutton, who refitted the building with hardwood floors and added a third storey. The building was renamed the Robinson Hotel and operated under that name until the late 1920s. Today, the building is known as Auberge Knowlton and is the oldest continuously operating hotel in the Eastern Townships. At the rear and left of the Auberge (yellow building), the original blacksmith shop used by stagecoaches on their passage through Bolton Pass still exists.

Built in 1868 on land donated by Thomas Lynch, the Church was enlarged to its present size in 1898, and a bell tower was added. The presbytery was subsequently built in 1905. In 1963, as a result of the growing Roman Catholic population in the area, the summer chapel was constructed.

Built in 1872, the general store was run by John S. and H.E. Williams, merchants. In 1948, the building became the home of the Canadian arm of Clairol, run by Paige Thornton, whose ancestors include the Pettes family. Today, this building houses a business known as Amalgamated Industries and is operated by a member of the Thornton family.

This Second Empire Victorian-style house, named Villa Sunny Lea, was constructed in 1876 by the Williams family. Subsequently, the Colby family, related to the Williams family and associated with the Colby-Curtis family of Stanstead, lived at Sunny Lea.

Built by Frank P. Williams of Knowlton, this house was one of three homes built by the Williams brothers circa 1880. Williams ran a mercantile business for many years in Knowlton. This house is an example of a Victorian neo-Gothic style of architecture. Today, the home belongs to Dr. and Mrs. William J. Barakett.

Built in the early 1870s and called the Lake View House, the Inn has always been a favourite destination for visitors. Recently renovated to its former grandeur, it boasts a fascinating historic wall in the lobby.

This High Victorian-style home was built in 1897 for Ernest Fleury, a local notary who also served the Town for several years as Mayor. The house was subsequently inhabited by the notary's daughter Annette Fleury, as well as other family members.

The H.F. Smith Printing Company, founded in 1882, occupied this Victorian-style house until 1899, when the house was sold to the Molson’s Bank. The Bank used the house as a branch office and manager’s residence for many years. Lovingly restored, the building has served in more recent years as a residence and holistic centre.

Nestledown was built in 1834 for Paul Holland Knowlton. Until 1860, it was located opposite its current location. Judge Samuel William Foster, who owned the house subsequently, had a tower added in 1887. The Nestledown house was later inhabited by the son of Judge Foster, George Green Foster, a prominent businessman and lawyer in Brome County.

Known as Darley Place, this brick house was built circa 1860 by Paul Holland Knowlton for his niece and adopted daughter Sarah Knowlton and her husband, Hiram Sewell Foster. Foster, whose family is among founding families of the region, was a prominent promoter and builder in the Eastern Townships. Darley Place was later inhabited by his son, Thomas Knowlton Foster. The residence originally had two floors, but the second was later demolished.

This house belonged to Flora Pettes Lynch circa 1880.
