What stands out about Cottage City’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Its history dates to pre-revolutionary America; old records indicate that the area was home to several of the Potomac River Indian tribes. With the coming of European settlers, the area became noted for its deep-water Anacostia River port, known then as Harrison's Landing. Contributing to the economy of Harrison's Landing was Moyer's Grist Mill located in Yarrow, the very first mill of its type between Baltimore and Alexandria, Virginia. Yarrow was renamed several times, but today we know Yarrow as Cottage City.
In 1923, according to Wikidata. the census of 1930 counted 938 people here.
