Bullock Texas State History Museum
Three floors telling the story of Texas, anchored by the recovered wreck of La Belle, a French ship from 1686 displayed as an actual excavated hull. Kids respond to the shipwreck, the Goddess of Liberty statue in the atrium, and the full-size artifacts far more than to the wall text. An IMAX theater on site runs both documentaries and current releases, which is a useful rainy-afternoon backup. Right across from the Capitol so you can combine both in one downtown trip. Free family days and hands-on carts run on select weekends.
