The historically-significant double-height library on the top floor of this Arts and Crafts townhouse features its original nautical maps, a seahorse chandelier and a mantle painting depicting the Bownell family ancestors’ arrival in New Amsterdam. Polychromatic tiles on the mantel surround showcase various knights in aristocratic tunics, doublets and armor, being that medieval times were common themes featured in the American Arts and Crafts period.
