The beach, a towel and some sun block may be all the activity you need, but Virginia Beach also has a host of historical attractions and museums. The Adam Thoroughgood House is a restored brick home from the 17th century and a prime example of early Virginia architecture, while the Old Coast Guard Station, housed in a restored coast guard station from 1903, shows the history of the coast guard and other lifesaving services, along with exhibits on the shipwrecks that have occurred off Virginia's coast. Virginia Marine Science Museum displays the state's marine environment through 800,000 gallons of aquariums, live animal habitats and more than 300 hands-on exhibits. Contemporary Art Center of Virginia focuses mainly on art of the 20th century, with rotating exhibits of American and international works. And then there's Mount Trashmore. As the name implies, this former landfill was covered with soil years ago and is now one of the highest and steepest hills in the Hampton Roads area. A thick carpet of grass and a well-maintained playground make it an enjoyable place to have a picnic or just explore.
