From the simplicity of the earliest Federal-period homes to the opulence of Victorian residences on tree-lined Central Avenue, Laurel's Historic District displays a veritable smorgasbord of architectural styles. The uniqueness of such diversity and the high survival rate of original building stock merited placement on the National Register of Historic Places, the largest such district in Delaware. Laurel also has two of the largest indoor/outdoor flea markets around. One covers twelve acres and is a destination point for bus tours up and down the East Coast. It was recently cited by Good Housekeeping magazine as one of the top fifty flea markets in the country. It is also the hub of furniture shopping on the Delmarva Peninsula, offering the region's three largest retailers.
