1879 Avery House

The stately sandstone Avery House was built in 1879 by Franklin Avery, who set the tone for Old Town's broad streets when he surveyed the city in 1873. You can tour the inside on weekends. The Avery House is just one of 36 sites on the Poudre Landmark Foundation's historic walking-tour map, which includes several self-guided options.
