LONDON — Art gallery Colnaghi enters a new chapter as Konrad Bernheimer, chairman of the 255-year-old firm, has announced a merger with fine art dealers Coll & Cortés (London and Madrid). Combining the strengths and expertise of both firms and diversifying their previous offering, Colnaghi will offer European Old Master paintings, sculptures and drawings, as well as art from the Spanish-speaking world.

A century after the firm moved from Pall Mall to Mayfair, Colnaghi will return to St James’s in 2016, moving from Old Bond Street to a larger, custom-built gallery where it will present international Old Master paintings, sculptures and drawings in a fresh context suited to the Twenty-First Century. The company’s celebrated and treasured library will sit at the heart of the building.

Colnaghi is expected to move to its new gallery in the first half of 2016, and will continue at the current premises on Old Bond Street until that time. The Coll & Cortés gallery in Madrid will continue to operate under that name for the foreseeable future. Further details of the new gallery will be announced at a later date.
