Auberge de Provance was built as the hostel of the French knights from Provance between 1571 and 1575 under the directions of Girolamo Cassar. The façade was remodelled in the mid-17th century and is attributed to Mederico Blondel (active in Malta 1659-1698).

The original façade of the auberge was set back from the present street alignment thus having a small square in front of it. In the mid-17th century a wing was added instead of the former square and the current façade was built along the alignment of the street.

The chambers of this two-storey building are roofed by diaphragm arches, quadripartite vaults and wooden ceilings consisting of beams and polychromed and gilded panelling. The entrance vault has an allegorical fresco.

The piano nobile has a parquet floor, mural decorations and a minstrel balcony.

The architecture is rather Mannerist, including the façade, which has pronounced rusticated quoins incorporating alternating bands of protruding rounded and square stone sections.

The ground and upper floors are divided by heavy cornices, while pairs of Doric attached pilasters at ground floor and Ionic attached pilasters at the upper floor divide the façade.

At ground floor the façade consists of arched openings for shops (botteghe) with mezzanine windows framed by scroll mouldings.

Auberge de Provance was used as the Thorn's Hotel in the early 1800s and later used as the Union Club in 1826. It is now the National Museum of Archaeology.

Mepa scheduled Auberge de Provance as a Grade 1 national monument as per Government Notice number 276/08 in the Government Gazette dated March 28.
