| Hardy Allen House: (Three Sisters Floral) Southeast corner of Main Avenue and Larch Street. Early settler and stockman Hardy Allen and his wife Daisy moved to Sisters in 1905 and built this fine house in 1908 on the corner of Main Avenue and Fir Street. The house was scheduled for demolition in the 1980s but was saved by moving it to its current location. It was renovated in 1990 to match its historical appearance. |

| Hotel Sisters: (Bronco Billy’s Ranch Grill and Saloon) Northwest corner of Cascade Avenue and Fir Street. The Hotel Sisters was built in 1912 by businessman and Spanish-American War veteran John Dennis. The nicely modern facility boasted hot and cold water in each of its 19 guest rooms and featured heat from a hot air furnace in the basement. It is one of the most photographed buildings in Central Oregon. |

| Leithauser General Store: (Sisters Bakery) The Leithauser General Store was built on Cascade Avenue between Larch and Spruce streets in 1925.

The building has housed a barber shop, a variety store, a yarn mill and a bakery. |

| Old Sisters Library: West side of Spruce Street between Cascade and Main Avenues (behind the Sisters Area Chamber of Commerce Visitors Center).

The library opened in 1939, with shelf space for 1,000 books. The building was moved to its current location in 1980 and it was retired in 1990. |

| The Palace: (Sisters Olive and Nut Co. and the Grand Palace Hotel) Southeast corner of Cascade Avenue and Elm Street.
