One of the early editions of Riverside Methodist Episcopal Church stands at the corner of Bird and West on the West Side, formerly known as part of Black Rock.
Seems the church moved around quite a bit, along with splitting into rival factions and then making up again. It started in downtown Buffalo around Franklin and Niagara somewhere, then moved on up river, continually upgrading.
This particular building was deemed to expensive to repair properly and sold to private interests for storage. It still maintains its spiritual look on the outside even though the insides were gutted long ago.
Meanwhile the congregation built another church on Baynes and Potomac, where another group now holds services.
