・In 1879, Father de Rotz came to the Sotome area to conduct missionary work, and he devotedly engaged in various welfare and philanthropic activities to improve the welfare and lives of local residents.
・Promoting agriculture was one such effort by Father de Rotz. In 1884, he started to cultivate wasteland in Shitsu Hendake to create farms.
・As part of efforts to develop wasteland, the Odaira Workshop was established. It is thought that the workshop was constructed in around 1901, when the cultivation was completed.
・This workshop is a one-story solid stone building with part of the front made of brick. The so-called “de Rotz wall” technique was used for the construction of the workshop. A clasp still survives today, which is said to have been used to yoke up the favorite horse of Father de Rotz.
