Hilton Princess San Salvador Hotel. The seismic nature of the San Salvador area has until recently hindered the construction of high rise buildings and skyscrapers in the city; however, with new technological advances and the advent of earthquake-resistant structures, high rise buildings have begun rising over San Salvador. Today the city has monuments, plazas, stadiums, high rise buildings, large malls and cathedrals built in Neo-Gothic, Modernist, Populuxe, Googie, Streamline Moderne, Art Deco and Futurist style architecture.
