Casa Julio Büttner & Sons - Local library and historical building

Founded in 1883 by the Büttner family, and considered as one of the most prestigious steam-powered carpentry workshops in Paraguay. In 1922 Julio Büttner acquired the Stanley generator, providing electricity to the whole town/city.

In 1925, he joined the ice making factory and in 1926 offered a car and truck service. That very same year the first passenger bus reached Asuncion. The Büttner home also functioned as the German and Agricultural Bank. In 1930 a telephone system and volunteer fire department were also added.

 Today the Büttner building is preserved as a library on the crossing of Colonos Alemanes and Nuestra Señora de la Asunción streets.
