Europe House)[note 1] is an historic late nineteenth-century Portuguese colonial building in the Bidau Lecidere [de] suco of Dili, capital city of East Timor.

Initially a Portuguese Quartel de Infantaria (infantry barracks), the building became the home of the municipality of Dili administration in the late 1930s.

[1] Although its official name was Fortaleza de Nossa Senhora da Conceição ("Fortress of Our Lady of the Conception"), it was better known as the Tranqueira ("Palisade"), because it was made of wood.

[2][3] Initiative for the replacement of that building with a more substantial structure came from a mid-nineteenth-century Governor of Portuguese Timor, José Maria Marques [de; pt] (1834–1839).

On 24 November 2008, Casa Europa was officially inaugurated by Dr Ramos-Horta and the European Commissioner for Development and Humanitarian Aid, Louis Michel.

[2] Its north side facing the sea is open, an arrangement made possible only because of a coral reef that gave the area natural protection from landings from enemy ships.

[2] The building's two lateral wings are topped with full length gable roofs, each featuring upright projections overlooking the street and the parade ground.

The central section has a symmetrical composition with an overhang borne on four columns denoting the main entrance, and is similarly fitted with a gable roof.
