If you leave from Porta udine, where you can still see, in its original location, the great wheel used to lift the drawbridge, then you turn right at the first side street and go along the Strada delle Milizie. This road went round following the line of the walls and allowed for quick movement and protection of troops and goods.
The Military headquarters overlook the road together with the buildings used by the artillery situated on the fortifications.
Along the route you can see:

Powder Store / Powder House

This was a depot for the stocks of gunpowder used by the artillery. Three of them were built between 1810 and 1811, while the three Venetian circular powder stores were destroyed.

The defensive Napoleonic Barracks of the Rampart.

This was the project of a General of the French military Engineers, Chasseloup, and dates back to 1808. On its façade there were the windows and doors(with a balcony) of the rooms with fireplaces for the soldiers, while on the façade towards the rampart there were slits for the fusiliers and for small pieces of artillery.
The ground floor houses the bakeries for bread making. During the siege of 1813 the Barracks were used as the seat of the Headquarters.

Laboratory of Powders

This was a building used for the working of powders, built by the French in about 1811.

St. Andrews Quarter

During the period of rule of the Republic of Venice, 12 quarters were built for the garrison . They were given the names of various Saints.
St. Andrews’ quarter was intended for the cavalry and was commissioned by the Provveditore Generale Andrea da Lezze in 1630

San Zuane (St. John’s Quarter)

This was built between 1625 and 1626 and was used by the cavalry, but in the middle of the1600’s it was changed into the soldiers’ quarters. It could house about 200 men.

Venetian square powder

A curious point to note: near the entrance of the Junior Schools (Porta Aquileia) is the oldest building of the town. It is a small Venetian square powder magazine which dates back to 1595. Nearby there is a small building with arcades built in the middle of the1600’s housing the public abattoir.
