Bolton Hill is a neighborhood with tranquil tree lined streets, small quaint urban parks with fountains that complement this period architecture of 19th century mansion homes and modern townhomes. Most homes contain plots of exterior space set out as hidden retreats or formal gardens that combine with the elegant buildings to make Bolton Hill an urban retreat in the city.

Most Bolton Hill residences were constructed between 1850 to 1900. Street front facades set them apart. Stone sills outline windows and liberal use of brown stone facade or massive grey stone at the base suggest very grand interiors. Iron fencing and gateways and patches of lawn-rare for 19th century row houses-define the homes as exceptional. Most houses exhibit massive marble steps and a liberal use of marble on the exterior. The Beethoven Apartments, in the 1500 block of Park Avenue, were erected in the 19th century as Baltimore first streetfront terrace or group of houses constructed to appear as a single structure.
