Lima's architecture offers a mix of styles. Examples of early colonial architecture include the Monastery of San Francisco, the Cathedral and the Torre Tagle Palace. These constructions are generally influenced by Spanish Baroque, Spanish Neoclassical and Spanish Colonial styles. After independence, preferences gradually shifted toward neoclassical and Art Nouveau styles. Many of these works were influenced by French architectural styles. Many government buildings and major cultural institutions were constructed in this period. During the 1960s, the brutalist style began appearing in Lima due to the military government of Juan Velasco Alvarado. Examples of this architecture include the Museum of the Nation and the Ministry of Defense. The early 21st century added glass skyscrapers, particularly around the financial district.
