Rancho Tranquilo

Address: 24889 Grandview Ave., Genesee Mtn. 80401

Agnes Reid Tammen, widow of the Denver Post co-founder Harry H. Tammen, purchased 15 acres on Genesee Mountain in 1930. She had a Spanish-style estate developed similar to those owned by entertainment tycoons in Santa Barbara, California - tile roof, wrought-iron trim, stone walls, patios and walkways. Architects Merrill and Bernham Hoyt employed excellent craftsmen from Mexico to beautify the 8,000 sq. ft. hacienda-style house with verandas, patios, and an outdoor "cantina" with enclosed kitchen, bathroom and grill. The estate includes water rights to a spring-fed well, water treatment system and sewage treatment system as well as a massive sprinkler system to protect the estate from wildfires. Other structures on the estate include a guest house, 12 horse stall barn, 7 car garage, a green house, and gazebo with a fountain. After Mrs. Tammen died in 1942, her niece, Helen Crabbs Rippey, lived there and her family operated a nearby turkey farm. The estate was owned by the Colorado Women's College in 1960 and has had several private owners since.
