The government house stands on the eastern end of the Plaza.
Its present construction dates from 1894 when it was merged
with the adjoining Customs and Post Office buildings. You
could also see the excavation that have revealed part of
the old Customs house. The "patios" of the Casa Rosada
are decorated with palm trees and fountains giving it a
Casa Rosada's museum is an interesting pot for visitors.
Casa Rosada is guarded by soldiers of the Granaderos (a
Caballo regiment-mounted grenadiers) whose uniform is the
same that was used since San Martin created the regiment
in 1813. A small platoon of Granaderos crosses the Plaza
everyday at 7 p.m. to lower the flag on the Plaza's flagstaff.
