St. Andrew’s Anglican Church is in the center of town. The name is derived from the Saint Andrew Parish, often referred to as the Big Parish. You will find a few 18th century buildings in this once thriving village. They include the police station, court house and post office. Grenville also has a Catholic church. The Gothic Revival landmark was built in 1841. The church closed for worship in 1923 and then repurposed as a primary school until 1972. Sadly, the church has been deteriorating ever since.
