The Banquitas House of Culture occupies a restored colonial-era building on the riverside in Orange Walk Town. The museum covers local history from the pre-Columbian Maya through the British colonial period, with exhibits on the sugar industry that has shaped the region's economy and demographics. It is small but well-presented, and the staff are knowledgeable about both the collection and the wider area.
The building itself sits in a pleasant riverside park — Banquitas Plaza — which is a good spot to watch the river and the town go about its business. The museum makes a sensible stop before or after the boat trip to Lamanai, providing background that helps make sense of what you see at the ruins.
