The Dexter Mausoleum located in section 20 of Spring Grove Cemetery is a private, family mausoleum, often mistaken for one of Spring Grove's three chapels. Dexter was a English immigrant - a "whiskey baron." His mausoleum was intended to resemble a Gothic Revival "funerary monument." Designed in 1869, it boasts the only two symmetrical buttresses in Cincinnati. It is registered as a historical landmark.
