St. Ignatius Church
The oldest continuously occupied Jesuit residence in the world, the Manor and Church is a pretty place to visit, with a good bit of history to its name. The mission was founded in 1641 to administer to the Potapoco American Indians. It was here that John Carroll was invested in his robes as the first Catholic bishop in the country (he later also founded Georgetown University). Outbuildings include a small, mid-19th century wood-frame slaves' quarter.
A good sized wooded county park with hiking and nature trails, playgrounds, and a 60 acre lake for fishing, pedal boating, rowboating, and canoeing.
