By the end of the 19th century the five entrances had disappeared from the city, so it was that during this time the Wall of Trujillo was torn down and allowed the growth of the city. This urban expansion allowed the establishment of the neighborhoods of Chicago, La Unión and Pedro Muñiz. During the administration of Don Víctor Larco Herrera as mayor, the city began upgrading works such as the construction of City Hall, the arrangement and embellishment of the Plaza de Armas and the atrium of the Cathedral. It also built the road to the resort of Buenos Aires, which expanded the city urban planning perspective. Another project was the renovation of the Municipal Theater.
