About Us | Keystone-Church

A century old tradition of warmly welcoming visitors to the Black Hills.

First Congregational Church of Keystone

Founded in 1895, and serving the community from the same historic building since 1896, invites all to take part in our events.

The service is traditional but informal. The Lord’s Supper is observed on the first Sunday of each month. All events are held at the Church building unless noted otherwise. Check out our dates for Church services in the park! Worship in the beauty of the black hills, held at Watson park. Sunday service starts at 10am.

The Church is located one block north of Highway 40 (up the hill from the Big Thunder Gold Mine) in Old Keystone at 402 Blair Street. It’s one of the featured sites on the “Keystone Walking Tour.”
