Palazzo Braschi displays a series of 18th-century drawings, sketches and designs from its own collection.

The drawings attest to the spate of construction of monumental buildings by well known architects such as Ferdinando Fuga and Nicola Salvi, including celebrated works such as the Trevi Fountain, the façade of St John Lateran, St Paul outside the Walls, and numerous chapels, fountains and private homes.

Due to their fragility, the paper works can only be exposed to light for short periods of time and are rotated by the museum which has a vast amount of drawings, watercolours and engravings in its care.
