Also referred to as the Mozart Museum, this 1787 villa is where the famous composer completed the overture to Don Giovanni—the night before it premiered. Though some displays have only a tenuous connection to the great composer, at least one recital each week features his work, and the interior is still from Mozart's time. The peaceful surroundings make a nice spot for afternoon coffee under the trees. Daily April-October 9 am-6 pm, November-March 9:30 am-4 pm. 110 Kc adults, concerts from 350 Kc. Mozartova 169 (5), Prague. Phone 257-317-465. http://www.bertramka.com.
