Project for the Royal Palace in Campo de Ourique
The Project for the Royal Palace in Campo de Ourique was an ambitious 18th century proposal for a monumental royal palace to be built in the Campo de Ourique neighborhood of Lisbon. Portuguese architect Dionizio de S. Dionizio planned the palace for King Joseph I of Portugal as part of the reconstruction efforts following the destruction of the 1755 Lisbon Earthquake.
