The nineteenth-century paintings in the entrance hall and the vestibule of the Hôtel Turgot are recent entrants to the collection of the Fondation Custodia. The 2010 bequest of nearly sixty paintings belonging to Carlos van Hasselt – an outstanding assistant to Frits Lugt, then the first director of the Fondation – form the backbone of this group. It consists largely of landscape oil sketches on paper by French, Danish, German and Dutch artists. This collection has grown considerably since 2010 and today comprises nearly three hundred paintings that illustrate the enthusiasm felt by artists, at the end of the eighteenth century, to work at painting rather than drawing in the open air.

Part of the collection of paintings can be accessed through the online catalogue of the 2012 exhibition Un Univers intime.
