commemorative plaque to Pedro Bigador

The commemorative plaque to Pedro Bidagor sits at Calle de Serrano 89 in Madrid's upscale Salamanca district. It honors a Spanish architect and urban planner who lived in this very building for three decades and left a lasting mark on the shape of the Spanish capital.

Who is being honored here?

Pedro Bidagor Lasarte was born in 1906 in San Sebastián and died in 1996. He ranks among the most influential Spanish urbanists of the 20th century, credited with institutionalizing modern urban planning in Spain during the Franco era. His best-known achievement is the so-called Plan Bidagor, Madrid's General Urban Development Plan, drafted by 1941 and formally approved through legislation in the mid-1940s. It was the first planning document in Spain to comprehensively regulate land use through zoning, setting out the city's growth via partial development plans. This plan is widely regarded as the starting point for what became known as "Greater Madrid" — the sprawling metropolis the city is today.

What does the plaque say?

The inscription states that Pedro Bidagor lived in this house from 1963 to 1996, identifying him as the architect-urbanist and author of the 1941 General Plan for the Organization of the Capital, the origin of "Greater Madrid." The plaque was installed by Madrid's city council in 2003, part of a broader municipal program that commemorates figures and moments significant to the city's history.

How do you get there?

The plaque is mounted on the facade of the building at Calle de Serrano 89, right in the heart of Salamanca — one of Madrid's most elegant and affluent districts, known for refined architecture, upscale boutiques, and wide tree-lined avenues. It makes a natural stop on a walking tour of the neighborhood, especially if you're already visiting the area's museums.

What else is worth seeing nearby?

Just steps away stands the Lázaro Galdiano Museum, one of Madrid's most compelling art and decorative-arts collections, housed in the former residence of collector José Lázaro Galdiano. A short distance away is another plaque honoring Antonio Hernández Gil, a Spanish jurist and politician. The surrounding streets hold numerous similar plaques, part of Madrid's extensive registry documenting the city's intellectual and architectural history.

When should you visit?

The plaque can be viewed year-round, as it sits on the exterior wall of a building along a busy street. Daytime visits work best, when natural light makes the inscription easy to read and the nearby museum is open. The Salamanca district is especially pleasant in spring and autumn, when Madrid's temperatures are milder than during the height of summer.
