Visit this wonderfully maintained Georgian town house and formal garden that was once the residence of Samuel Powel, Philadelphia's first mayor after the revolution. The Mayor and his wife, Elizabeth Willing were the preeminent hosts, who frequently entertained the famous names of the Revolution. Visit the drawing room where George Washington danced, ponder John Adams ''sinful feast,'' and stroll through the tranquil garden. 40-minute guided tours available Thursday-Saturday noon to 5pm, and Sunday 1 to 5pm.
