Moore's Fort, Blockhouse in Round Top, Texas.

Moore's Fort is a twin blockhouse structure with defensive features like gun ports and thick wooden walls. The two building sections are connected by an open passageway, a typical layout of early Texas settlements.

John Henry Moore built this fortification in 1828 in response to Comanche raids threatening the region. It was later moved from its original location in La Grange to Round Top and remains the oldest structure in Fayette County.

The name recalls John Henry Moore, who built the blockhouse in 1828; the two log cabins joined by an open dogtrot passage are the layout visitors can still walk through. A historical marker stands at the original site in La Grange, where the fort first sheltered settlers.

The fort stands in Round Top, while a historical marker marks its original site in La Grange, so plan to visit both to follow the story. The structure is a log blockhouse with an open dogtrot passage, so expect uneven ground and no modern facilities on site.
