Both twin neighborhoods are on steep valley slopes with many original thick-walled stone and brick millworkers houses with pitched roofs and dormer windows for second floor or attics of the 1800s, along with later versions of typical early 20th century Baltimore style rowhouses, plus some century-and-half old wood-frame or shingled cottages with tiny front yards.

It is surrounded by numerous other massive stone and brick large mills and factory complexes (similar to New England typical mill towns) up and down the often frequently flooding stream, dating to the early 19th century and the beginnings of the Industrial Revolution for making flour, cotton canvas duck cloth and various foundries and machine shops which were active into the mid-20th century.

[2] It was home for three decades to the Londontown Manufacturing Company, Inc., founded 1922–1923 by Israel Myers for making what became the world-famous London Fog outerwear / all-weather rain coats.

The complex was heavily damaged again during the floods resulting from Hurricane/Tropical Storm "Agnes" in June 1972 which devastated the Middle Atlantic states / Chesapeake Bay region.

Londontown Manufacturing Company, Inc. in its old Meadow Mill buildings / campus was listed on the National Register of Historic Places in 1973, three years before its move to Eldersburg, Carroll County.
