The mansion, which takes its name from a former mendicant order in Syria, was initially built as a convent. Construction work on it began in 1724 and was finished in 1729, thanks to funding obtained by the nuns from Duchess Marie-Célestine de Holstein-Rethwisch.
In 1792, in the fury of the French Revolution, the outside chapel and part of the cloisters were destroyed before the buildings were rented, between 1801 and 1863, by a private owner to the local authorities to host the police services and prison. It was then purchased in 1927 by the municipality and transformed into a hospice which was officially inaugurated in 1933. In the meantime, between 1873 and 1885, it was revamped as a stately home for the Moreau de la Tour-Godard-Desmaret family. Lastly, from 1979 to 1983, as well as in 1989, the building was modernised with an extension to the south, part of which was demolished several years ago.
An entrance porch with a slate roof leads into the grounds in front of the mansion to the east. The main façade, with three storeys, stands out thanks to its brick and stone settings as well as the symmetry of its central section. In the second half of the 19th century, a scroll pediment and two balconies were added to the initial construction of 1724, on the western façade. Additionally, the main section has a half hipped slate roof dotted with hipped dormers and a chimney stack. To the north, there is a wing with a square tower topped by a slate pavilion roof with a zinc ridge cap, while to the south there is a wing with a similar roof.
To the west, two flights of stone steps lead down into the grounds, which spread around the mansion over approximately 7,000 m² and include lawns and copses as well as almost 1,000 m² which can be built upon.

The mansion

This rectangular building has two levels topped by an attic. The masonry-work is in brick, while the sleeper wall, belt courses and quoins are made of limestone. The slightly arched window frames are made of an alternation of bricks and limestone blocks. On the western façade between the two lowest levels, there is an old coat of arms carved into the stonework. Above it, in front of the roof, there is a sculpted great helm housed in an arched alcove, on either side of which there are plasters and arched windows, underlined by moulded cornices and crowned by a brick and stone pediment with a flame urn at the centre. On either side of the central section, two French windows on the first floor each open onto balconies supported by three caryatids, depicting men wearing cowls.

The ground floor
From the porch on the northern tower, an imposing glazed door opens into a hall, from where the main staircase with wooden balusters climbs up to the first floor. The floor is paved with tiles and there is a lavatory under the staircase. To the left, a double-leaf door opens into a large, vaulted corridor, into which light streams through six stained-glass windows depicting coats of arms. At the end, a double-leaf door leads into the former chapel with a vaulted ceiling, while to the right two similar doors lead into a large lounge, also boasting semi-circular arches. On either side of the room, there are two fireplaces. One, a period Louis XV fireplace in brown marble, is topped with a trumeau mirror while the other is made of sculpted marble. The lounge is bathed in light through four small-paned windows and a set of French windows that open onto the grounds. A door leads into a cloakroom with a sink as well as to a second lounge after the other one, from which a small-paned, double-leaf door leads out into the grounds. After the second lounge, there is a third one with a spiral staircase leading to a mezzanine. It boasts an old rococo trumeau mirror topped by a sculpted crown. Lastly, from the corridor, a passage leads to a room in which there is an elevator as well as a second wooden staircase leading up to the two upper floors.
The first floor
The main staircase leads to a landing into which light pours through a window with stained-glass made up of bottle bottom patterns. A corridor leads to eight bedrooms, each of which boasts a washbasin and small-paned windows. There is wood stripped flooring throughout covered by linoleum. At the end of the corridor, there is a landing from which the elevator can be reached as well as the second wooden staircase, from which, through a door, an entresol on the first floor of the extension can be reached. This level also includes an old kitchen and three lavatories. Lastly, a wooden staircase leads to the top floor.
The second floor
This level can be reached by the second wooden staircase and is made up of a small landing paved with terracotta tiles and two small rooms on either side. A passage leads to a vast loft, paved with brick and boasting exposed roof framing that is in good condition, which occupies almost the entire surface of the mansion on this level. Light filters into this level via dormer windows in the east and west wings. Although the attic has not been converted, it has the potential to be transformed into further living space.

The extension

This part of the edifice was built in the 1980s and can be reached via a separate entrance but also via the original mansion. It boasts floor space of approximately 1,000 m² spread over three levels, as well as cellars.

The ground floor
This level can be reached via the main entrance and is made up of a vast hall leading to a dining room, with patio door windows overlooking the grounds. To the right, there is an office and a lavatory, while a door leads into the original part of the mansion. To the left of the hall, a passage leads to the kitchens, offices, a former smoke room and two bedrooms. Following on from the corridor, a door opens into another corridor which leads to sixteen bedrooms, with a hallway leading to lavatories and a shower room. Lastly, further on, a lounge opens onto five other bedrooms. Three staircases lead to the first floor.
The first floor
This level can be reached via three staircases located in the extension as well as from the mansion. It is split into two parts: in the first, a corridor leads to six bedrooms and a dining room; in the second, there is a former sick bay, a former kitchen and a corridor leading to sixteen bedrooms, lavatories and a bathroom. A hallway also leads to seven extra bedrooms.
The second floor
Two staircases in the extension climb up to this last level, which is made up of a corridor leading to a lounge and a lavatory plus sixteen bedrooms and a bathroom, also equipped with a lavatory. A door leads to another lounge, from which seven extra bedrooms can be reached. A staircase climbs up into the not yet converted attic.
The basement
This level is split into two separate parts. The first, which extends beneath the mansion, can be reached by an inside staircase as well as via two outside doors. It is split into seven cellars. The second part can also be reached via an inside staircase as well as several entrances from the grounds and is located beneath the extension. A corridor leads to a laundry room, various stores and the boiler room, while a hoist communicates with the different levels of the extension.
