The village of Glendale is located in southwestern Ohio, about north of Cincinnati. Its historic core is an area of about , bounded roughly by Coral and Washington Avenues on the north, Springfield Pike (SR 4) on the west, Oak Street on the south, and South Troy Avenue on the east. South Troy parallels railroad tracks, and the village's business district basically straddles those tracks near Sharon Road. Congress Avenue is a major road passing through the district north from the junction of Springfield Pike and Oak Street. The area east of Congress Avenue is heavily residential, with winding roads and mature landscaping. There are two small parks in this area, both on East Fountain Avenue, which travels generally southwest to northeast. Houses in the district are mostly either Italianate or Second Empire, reflective of the village's development period in the 1850s. The railroad depot included in the district holds a museum of memorabilia of the village's past, including when John Hunt Morgan went through the village on his great raid.
