Toward the turn of the 20th century, the Dallas elite began to abandon the area that now comprises the Arts District and move east (near the modestly funky Lakewood neighborhood). Sprawling, grand homes from the early 1900s -- English Tudor, Georgian, Spanish, you name it -- line a broad avenue, about 4 blocks of which are listed in the National Register of Historic Places. The Wilson Blocks (2800 and 2900), named for Frederick Wilson, who built a number of the homes there, are especially attractive. Around the holidays, Swiss Avenue is a favorite for Christmas lights cruisers. A drive-by can be done in 15 minutes; allow a half-hour if you want to stroll.
