The Union Chapel in the summer colony of Twilight Park in the Catskill Mountains of New York, is one of the finest late Victorian chapels in the region. The edifice was built in 1897, a year following the erection of the All Angels Episcopal Church, in Twilight Park, and was designed to complement the rustic character of the surrounding cottages. The chapel was built as a non-denominational, or Union church, for summer residents of the colony who preferred an alternative to Episcopal sermons down the dirt road. The church was designed by Alice Hands, of the New York firm Gannon & Hands, the first all-female architectural firm in the United States. The chapel was eventually closed in 1970 and converted to a private residence, with some stained glass windows donated to the Episcopal Church in Twilight Park.
