The San Salvatore Counterguard, and the faussebraye that houses the Sa Maison Gardens, viewed from the road below at the Msida Marina
The Polverista Curtain
If you walk by the Msida marina, you can see the Polverista Curtain – a long, casemated curtain wall that joins the Msida Bastion on the left, which houses the Msida Bastion Historic Cemetery today, and the La Vittoria Bastion on the right. The Maltese armed forces’ naval base, at Haywharf, is right beneath the Polverista Curtain. Its title comes from the construction of a gunpowder factory on the site, erected in the late 17th century after its removal from Valletta, which is why the structure is enclosed within a high-walled rectangular enclosure.

Sa Maison and the Skewed Arch
The Sa Maison gardens (Ġnien tal-Milorda) are inside a protective faussebraye, which is actually part of a wall that stretches along the entire width of the land front of Floriana, added by Valperga in 1670. The wall served as a shield for the base of the main ramparts.
To understand the scale of this wall, it was in the 1720s that the Portes des Bombes – today the main gateway to Floriana and Valletta – was built into the faussebraye as a single gateway arch.
Keep walking to the end of the Sa Maison gardens to find the large, skewed arch, known as the ‘arcone’, a design attributed to the Maltese architect G. Barbara. Today the skewed arch is integrated within the four-storey structure of MICAS. This arch provided an internal communication tunnel that leads to a set of three countermine galleries inside the counterguard.

The San Salvatore Counterguard
While you’re in the Sa Maison garden, know that you are also standing beneath the San Salvatore Counterguard.
The counterguard further protected the Bastion of Provence (also know as the San Salvatore Bastion). The San Salvatore counterguard is a massive earthen massif, that was used to reinforce the Bastion of Provence. It contains a number of gun platforms.
The San Salvatore Counterguard will be the site of MICAS’s sculpture garden, to be completed in 2026.
The MICAS Galleries are located in the section of the fortification that is at the edge of the Counterguard where the skewed arch ends.

The San Salvatore bastion
Once you enter the main MICAS esplanade, with the MICAS Galleries to your right, you will encounter the large San Salvatore Bastion (or Bastion of Provence), which was actually constructed before the counterguard.
In WWII, the bastion was equipped with two gun emplacements. In peacetime, it hosts government offices.
Originally, the San Salvatore Bastion was a large, retrenched bastion with its own built-in ritirata. In the 18th century, the new layout came to include the San Salvatore counterguard and a ditch.
The bastion also contains various communication passages and sally-ports, one of which opens out into the MICAS esplanade.

The La Vittoria Bastion
You will spot the La Vittoria Bastion, as the site of Conrad Shawcross’s Beacons, as well as the structure for MICAS’s art workshops and residences.
Built after 1670, the bastion consists of two parts – the upper level with a courtyard enveloped by the casemates, and a terrace platform with cannon embrasures; and a lower level consisting of vaulted interior spaces and magazines. One of the rooms inside the interior was converted into a 19th century gunpowder magazine.
The various levels of the bastion are still linked by flights of steps and two sally-ports, with a third opening providing access to the countermine inside the Bastion of Provence.
