Henkel Square is the historic heart of Round Top, a collection of preserved 19th-century buildings centred on the original Fayette County district courthouse. The courthouse is a simple wooden structure, and its survival is remarkable in a state where such buildings typically fell victim to fire or were replaced by grander masonry successors.
The surrounding square includes period homes, a dogtrot blockhouse (Moore's Fort), and a Lutheran church. Together they give a vivid picture of what a small Texas German settlement looked like in the mid-1800s. The square is walkable and free to explore on foot; some buildings are open for tours at certain hours. The setting is particularly attractive in spring when the wildflowers are out.
