One of Sileby's most distinguishing features is the Anglican church of St. Mary founded around 1152. It is a Grade II* listed building. The Gothic tower now houses a fine ring of 10 bells, which attract ringers from far and wide.
Sileby Mill Boatyard is an independent family run business established in 1985 on the site of a watermill dating back to the 9th century A.D. The mill, now a residential building, still retains the original wheel chamber and fittings.
The boatyard offers a full range of boatyard services including day hire on purpose built all weather narrowboats, a well stocked chandlery, moorings, and a busy slipway and servicing division.
