The Carlos de Amberes Foundation, located in the Salamanca district, is a non-profit private cultural institution. Its creation is the result of the desire expressed by a Flemish man to bequeath his entire fortune to Madrid in 1594 to create this institution and is still fully active four hundred years later.
The current headquarters are located in an old hospital - deconsecrated church, turned into a cultural centre.
The foundation promotes programmes and activities in the humanistic and scientific fields. Today, it carries out diverse activities, such as exhibitions, concerts, courses, conferences, etc. Its updated programme can be consulted on the official website.
Among the works of art housed at the centre is the masterpiece by Peter Paul Rubens, The Martyrdom of St. Andrew. The painting has been owned and safeguarded by Fundación Carlos de Amberes for more than 380 years, and can be enjoyed free of charge in its former chapel.

Furthermore, its rooms display the painting “The Martyrdom of Saint Andrew” by Pedro Pablo Rubens, which can be visited from Monday to Friday.
This painting historic, a property of the Carlos de Amberes Foundation, was commissioned to Rubens by Jan van Vucht, a Flemish citizen who lived in Madrid as an agent of the famous printer from Antwerp, Balthasar Moretus, leaving it on his death in 1639 to the San Andrés de los Flamencos Hospital, origin of today’s Carlos de Amberes Foundation. In the same will, a frame was commissioned for the painting, which is the original that we can still see today.
It is an absolute masterpiece from the end of the Rubens period, which he finished painting just one year before his death. In it, his colour palette inspired by the free, loose and luminous brushstrokes of the Venetian Titian stands out, along with his great dynamically Baroque compositional skill, as well as the great narrative clarity and the game of expressions and gestures that made him famous throughout Europe.
As a result of the renovation work being carried out at the foundation, the painting was moved to the Prado Museum at Mars 2025, exhibited in its original frame. It will remain there until summer 2026, when it will return to the foundation after the opening of the large new gallery that is double the size of the current exhibition space, making it one of the largest in the local area, along with modern new auditorium. The aim is to continue fulfilling the foundation’s centuries-old mission, while providing a better and more adequate response to the challenges of the 21st century.
