Chapel in a (Roman Catholic) cemetery in Koblenz, Germany.
The chapel in the German (Roman Catholic) cemetery in Krasnoe, Ukraine (formerly Krasna, Bessarabia, Russia) is designed like this one, and was used as a model for the one in Krasnoe. Max Riehl and his group of former Krasna residents paid for most of the cost of erecting the one in Krasnoe. Max lives in Koblenz.
