There are places that are simply the center of a city, and there are places that are the origin of everything that came after. Lima’s Plaza Mayor is both. Francisco Pizarro laid it out on January 18, 1535 as the point from which the grid of the City of Kings would be organized, and that layout still serves today as the core of Lima’s historic center. Nearly five centuries of Peruvian history have passed through this space: the arrival of the first viceroys, the Inquisition trials, the proclamation of independence in 1821, and the celebrations and protests of the republic up to the present. Everything began here, and everything still converges here.

The original layout and the ordinances of Charles I
The founding of Lima was not improvised. In 1523, King Charles I of Spain issued the Ordinances for the Foundation of Cities in the New World, which established that every new city should be laid out in a grid centered around a main square. This square would organize all the buildings of power: the cathedral, the governor’s palace, the city council, and the homes of prominent residents.
Pizarro followed these ordinances exactly. The square he designed in 1535 was large and well proportioned. According to chronicler Bernabé Cobo, it was the most impressive square he had seen, even compared to those in Spain. It occupied an entire block, and its layout defined the orientation of all the surrounding streets. That original grid, known as “Pizarro’s layout,” is still clearly visible in today’s historic center.
The bronze fountain: the oldest element
At the center of the square stands a bronze fountain, one of the oldest objects in Lima still in use. The first fountain was commissioned in 1578 by Viceroy Francisco de Toledo. The current structure was redesigned in copper by artisans Pedro de Noguera and Antonio de Rivas and inaugurated in 1651, crowned with an allegorical figure of Fame. This baroque monument has preserved most of its original structure for more than 370 years, surviving earthquakes, floods, and political changes.
The fountain is the main visual reference point when entering the square and best conveys its scale. Around it are gardens with palm trees, marble benches, and lampposts that reflect the neocolonial redesign introduced in 1939.
The four buildings that define the square
The Plaza Mayor has four sides, each defined by a historic building with its own architectural and institutional importance.
The north side is occupied entirely by the Government Palace, also known as Pizarro’s House, which is the official residence of the President and the seat of the executive branch. The current yellow facade, inaugurated in 1938, visually dominates the square. Every day at noon, the changing of the guard takes place with a military band and formal uniforms.
The east side is occupied by Lima Cathedral, whose construction also began in 1535 and which is now the primate basilica of Peru. Next to it stands the Church of El Sagrario.
The south side includes the Municipal Palace and the Club de la Unión, the oldest social club in Lima. The Municipal Palace features neocolonial architecture with carved wooden balconies.
The west side is occupied by the Archbishop’s Palace, famous for its carved wooden balconies, among the most photographed in Lima.
The history that took place here
During the Viceroyalty, the square was much more than a symbolic space. It was the main market, the setting for bullfights, and the stage for Inquisition trials. It was also where General José de San Martín proclaimed Peru’s independence on July 28, 1821.
This historical weight makes the square not just visually impressive but one of the most meaningful urban spaces in South America.
Pasaje Santa Rosa and surrounding streets
Several streets extend from the square, including Jirón de la Unión, the main pedestrian street connecting Plaza Mayor with Plaza San Martín.
Pasaje Santa Rosa offers restaurants and cafes in a quieter colonial setting, ideal for dining near the square.
At night: the illuminated square
At night, Plaza Mayor transforms completely. Lighting highlights the architecture and creates one of the most striking night scenes in South America.
The square is open 24 hours a day. During the night, the atmosphere becomes calmer and more relaxed.
Practical tips for visiting
The square itself is free to visit, but surrounding buildings have specific hours and entrance fees. The best time to visit is between 9:00 am and 11:00 am.
The area is generally safe, but it is recommended to stay aware of personal belongings.
