As Riga’s pharmaceutical factories were unable to produce the required amount of medication, in 1968 the construction of Olaine Chemical-Pharmaceutical Plant was started. It was one of the most important five-year construction projects, along with the construction of Riga HPP and Inčukalns gas storage. The construction of the plant lasted three years, and during its process the surrounding environment changed significantly: the place where the factory was built was marshy, with small sand dunes.
