What if a building could shed its skin and be reborn? St Mark’s, Mayfair has done just that. This Grade I listed building stands on North Audley Street. It has lived many lives.

Originally, St Mark’s was built between 1825 and 1828. This was to serve the growing population of Mayfair. Aristocrats and the wealthy needed more townhouses. John Peter Gandy designed it in the Greek Revival style. St Mark’s became one of his finest neo-classical works.

Fast forward to 1878. Architect Arthur Blomfield made substantial changes. He introduced a Romanesque style with an open roof structure. The facade is 34 feet tall. People regard it as one of the finest in London.

St Mark’s has served many roles. During World War II, it was unofficially known as The American Church in London. Its proximity to the United States embassy made it a hub for American worshippers. Even President Dwight Eisenhower and Eleanor Roosevelt visited.

In 1949, St Mark’s hosted a royal wedding. George Lascelles and Marion Stein exchanged vows here. King George VI and other royals attended. Benjamin Britten composed a special wedding anthem for the service.

But the congregation dwindled. By 1974, St Mark’s was deconsecrated. It sat empty for years. Historic England placed it on the “Buildings at Risk” register.

Grosvenor Estates acquired St Mark’s in 2014. They saw its potential. In 2018, GSA was commissioned to convert St Mark’s Church into a cultural hub. It should also be a sustainable community market.

Today, St Mark’s is Mercato Mayfair. It is a food hall operated by Mercato Metropolitano. The transformation has breathed new life into the building. It had been underutilised for decades. The interior, closed to the public since 2009, is now open. It offers retail, community, and cultural experiences. These are unique to Mayfair.

Mercato Mayfair features food stalls from multiple cultures. A rooftop terrace offers city views. The basement crypt now serves as a wine cellar and microbrewery. Cookery classes and events are held here.

Designers ensured that the modifications were reversible. This preserves the building’s flexibility. It ensures its longevity and continued conservation.

Donald Insall Associates restored the historic features. They repaired the stained glass windows. Polychromatic brickwork gleams. Mosaics and tapestries add splendor.

The project was commended at the London Planning Awards 2020. It won in the Heritage and Culture category. St Mark’s continues to nurture the local community’s affection. It cherishes this special part of urban history.

So, as you stand here, remember the many lives of St Mark’s. From a grand church to a vibrant food hall, its story continues to evolve.
