Heritage Open Day: Join us for a self-guided exploration of our church silverware. Pictures describing its history and use. Stewards will be on hand. Holy Trinity church is a 19th century church in a 13th century style, consecrated in 1851. It was built to serve the growing hamlet of Bracknell, expected to expand with the coming railway. The building and grounds, now grade II listed, have adapted within the new town. Inside there are many memorials/plaques/plates dedicated to the history of local families.
