There was a Methodist Church built there in 1847 and the first Orange Hall was built just to the east of it.The Mansfield school, School Section No.6, was built at the corner of Mansfield Road and Conley Road but was later moved to just east of Conley
Road, where it still stands. Mansfield was also the site of Goulbourn's first town hall built in 1853. It was on Carleton Cathcart's property and he was the township's first clerk. Unfortunately the building burnt down in 1872, and all the township's early records were burned with it. The building was replaced by a new township hall at Stanley's Corners which now houses the Goulbourn Museum. The village eventually diminished in size and disappeared as improvements in transportation led to people migrating to
larger communities.
