The work of Aaron Prentiss Howland (1801–1867) occupies a distinctive place in the architectural landscape of Walpole, New Hampshire. A direct descendant of Mayflower passengers, Howland was a carpenter, master builder, and civic leader whose Greek Revival buildings embody the optimism and ambition of the early American republic. One of his best-known surviving works is the residence at 20 Westminster Street, built circa 1834 and remarkably well preserved through nearly two centuries of careful stewardship.

This site explores the history and architecture of the Howland House, the lives of its successive owners, and the village setting that gives the house its meaning. A companion walking tour interprets 20 Westminster Street as part of a cohesive historic streetscape — one of the finest collections of Greek Revival architecture in New Hampshire.
