After the World War two, it seemed like the private enterprising will continue developing together with the town. Nevertheless, after the nationalization after February 1948, the textile production got to the very edge of the governmental interest. That’s why the fact, that at the place of the former textile production, a machine industry gained ground as well, was important for the town. A few years later, this one even predominated over the textile production. Strict centralization confiscated the main part of the town’s incomes from an enterprise and Červený Kostelec as the former “city of millionaires” got only scrap of them. In the 1950s` the housing construction stopped completely and its dynamics was resumed since the 1960s` thanks to the cooperative building society members and private persons. Out of their work arose the Koubovka and Kaštánek housing estates, the colony of family houses in Větrník, Lánská street, at Vyšehrad, in Lhota and Horní Kostelec. Lhota and Horní Kostelec together with Mstětín became part of Červený Kostelec in 1950. Later, Bohdašín and Olešnice joined as well. This way, there was formed a center, which had 9000 thousand citizens in the 1980`s. They year 1989 brought a transformation of a society and made possible a consistent privatization of services, trade, smaller companies and big industry in Červený Kostelec as well. The further town development was subjected to the sewage treatment plant construction. The sewage treatment plant construction and 13 km of the wastewater down comer were put into the operation in 1998. In consequence, Czech and foreign firms built their plants in the western industrial zone. In the new ground plan, the town takes into account the second, northern industrial zone with areas for housing and recreation together with a solution of traffic problems in the centre. The town, which lies mostly in the basin, is wholly gas-equipped by now, which brought a marked improvement of the air. In the town centre, in all their beauty, the reconstructed historical and old buildings are being used functionally (the town hall, Václav Hejna`s elementary school, the Sokol house, the basic art school). Modern architectonical elements were brought to the town with newly built Anežka Česká`s hospice, the U Jakuba house with a day care, the secondary industrial textile school as well as private houses. Červený Kostelec is a natural starting point to the beautiful valley (to the Jestřebí mountains, the Úpa river valley and the nearby ponds Brodský and Špinka) with a dense net of paths for tourists and cyclists.
