Frog Level, Plantation house in Columbia County, United States

Frog Level is a two-story wooden house with a temple portico featuring four columns on each level and two rooms per floor. The structure stands near Magnolia and was designed as a residential building on a plantation property.

William Frazier constructed this residence between 1852 and 1854, creating one of the few remaining plantation houses in southwestern Arkansas. The building dates from a period when such residences were a key part of the rural landscape.

The house was named Frog Level soon after it was built, because of the many frogs in the surrounding area. It is one of the few surviving slave plantation houses in southwestern Arkansas, built by William Frazier in 1852-54.

The house sits on the north side of County Road 148, west of County Road 27S and is marked as a National Register of Historic Places site. Visitors can observe the exterior architecture, which displays characteristic features of early regional construction methods.

Frog Level was listed on the National Register of Historic Places in 1972, one of only a handful of slave plantation houses still standing in southwestern Arkansas. The name was given soon after construction, when frogs were so numerous in the area that they supplied the house's identity.
