St. Moriz is the main Protestant church of Coburg, a Gothic hall church begun in the fourteenth century and finished in the fifteenth. It stands just off the market square, its twin towers a reference point across the old town. The interior is large and relatively unadorned — Protestant Coburg stripped the medieval decoration during the Reformation, which Martin Luther himself watched from the Veste above.
What survives is worth seeing: carved stone epitaphs of the Coburg aristocracy line the walls, and the high altar is an impressive late-Gothic piece. The church played a central role in the Reformation — Luther preached here and corresponded intensely with the congregation during his months in the fortress above. A small plaque marks the pew where he sat.
