At the beginning of Donja Raša, the lower, workers’ part of town stands the comfortable three-storey building called Type F1 Building with the total of 22 rooms which once housed single officials. Likewise, there was a Type F1 Building, a two-storey building with six mini-apartments for single engineers, erected in the upper part of town behind the church. Both of these were converted into residential objects after mine closure in 1966. It is interesting that after converting of Type F1 the area suffered tuberculosis epidemics, and this building served as a temporary quarantine accommodation for patients, mostly children, to be isolated from uninfected population. The epidemics, caused by infected water well sources Kokoti and Fonte Gaja, affected almost the entire Labin area in spring at the beginning of 1970s. The case was covered up for decades after the epidemics.
