The old Iloilo Provincial Capitol () was the office of the provincial government and official residence of the governor since 1849 with the original structure made out of wood and stone. The new modern Iloilo Provincial Capitol was constructed just behind the old provincial capitol and was completed in 2006. It was designed by Architect Guillermo Hisancha. The old provincial capitol has been renovated and restored to its former glory and is now being used as a lobby and reception area for visiting guests and dignitaries. In front of the capitol stands the Arroyo Fountain built in 1928 in honor of Senator Jose Maria Arroyo from Molo, Iloilo City who sponsored a bill creating the Iloilo Metropolitan Water Works. The fountain also serves as the Kilometer Zero or a point of reference in measuring distances in the city and province of Iloilo and also to various points and destinations in Panay Island from Iloilo City.
