he “Casa Hacienda Shismay” was built by Tyrolese immigrants who arrived in Peru in 1857 on their way to Pozuzo. These immigrants stayed in Shismay from September 1858 to 2 July 1859; at that time the house was owned by the Arrieta family. This is described in “Monografía eclesiástica de la diócesis de Huánuco y Junin 1934” by Monsignor Berroa. Some of the architectural details demonstrate European influence, such as the central heating.
     Later the property belonged to Mariano Ignacio Prado former president of Peru (1865 - 1868 and 1876-1879). After his death in Paris in 1901 the Hacienda Shismay was the property of Antonio Ingunza.
     Since 1924 the Hacienda Shismay belonged to the Rolando Tello family and later to Don Javier Rolando Tello. He built the road, connecting his estate with the city of Huánuco and transformed Shismay into the largest dairy and beef supplier in the Department.
     On 8 September 1979, due to the Agricultural Reform, ownership of the estate went to the hacienda’s workers and their families. They organized themselves as a community and took the name of  “San Sebastian of Shismay” in honour of the patron saint.
     The members of the community looked after this massive building for many years, but eventually due to the deepening economic crisis the house was left to ruin.
     In March 2004, the community of San Sebastian of Shismay received a generous private grant for the restoration of the “Casa Hacienda” and conversion of the hacienda warehouses into accommodation suitable for tourism.
