The Platform Tavern dates back to 1873 and is of historical interest as it is built against the old town wall built around 1350. The wall can be seen in the bar the stonework exposed to show its original state. The town wall was washed by high tides until the Eastern Quay was built around 1830. The house name is derived from its proximity to the Quay outside God's House called The Platform which contained a gun battery for ceremonial purposes.

Carrollton Black Cemetery Carrollton’s early African-Americans, many of whom were former slaves, helped settle and build the community. By 1871, this portion of forty acres belonging to Scott Boswell, Sr., an African-American farmer, was a community cemetery. In 1915, C.B. Baxley acquired the cemetery and surrounding land. Although the site holds dozens of burials, only three names (Ned Welch, Loving, and Davis) are now visible. Joyce Collins (1960) is believed to be the last burial. No records exist for others buried here; flooding from the Elm Fork of the Trinity River destroyed many grave markers. Once threatened by new development, the site is a precious record of the early history of Carrollton. Historic Texas Cemetery – 2010 Marker is Property of the State of Texas
