Question: Passage: Han Groenewegen worked in the Hague as a freelance architect from 1920 to 1927. Before establishing his own firm, he used to work for the contractor R. Rutgers in the Hague. One of his few works in the Netherlands is the Church of the Holy Heart of Jesus in Schiedam. During the Great Depression, Groenewegen left the Netherlands to established his own new firm in the Dutch East Indies. Many other architects were left for the Indies during the period, e.g. Albert Aalbers. Groenewegen arrived in Medan (on the island of Sumatra) in 1927 to work on the plan for a hospital, the St. Elisabeth's Hospital (1929-1930). He was active in Medan from 1927 to 1942 to work for the Oostkust. Like Schoemaker for the city of Bandung, Gronewegen can be considered as representative of modernist Nieuwe Bouwen in Medan. Among Groenewegen's extensive portfolio in Medan are the expansion of Medan Cathedral (1928), Arnhem Insurance (now Museum Perjuangan TNI, 1930), the Roman Catholic Chinese church in Polonia (1934), Princess Beatrix School (now Immanuel Christian School, 1938), Medan swimming pool (1939), and Oranjeschool (1941). Unlike many of his colleagues however, Groenewegen remained in Indonesia following the independence of the country.
