Under the management of architect Şerban Sturdza,  Union Square was reconditioned in 1988.
To mark the occasion a plan of the Habsburg fortress in 1730, with its 9 bastions, was engraved on a pavement stone.
At the time it was believed that this was all of the fortification.

In 2006 excavations for foundations in the Eugeniu Bastion area uncovered the counterguards of the bastion, the trench of the moat between the counterguards and a weir.
This was archaeological evidence of the three fortified belts of the Fortress.
After being mapped and photographed they were demolished.

In 2014, as part of the "Rehabilitation of public spaces in the historic center of Timișoara" project, a preventive archaeological excavation in Unirii Square confirmed the position of the Ottoman fortifications according to the Perrette map, as well as confirming their composition of earth stabilized with wood.
As a part of the same project, during excavations at the intersection of the Dimitrie Cantemir Street and Lucian Blaga Street (in the southeast corner of the Liberty Square), stone walls bound with mortar from the northern wall of the Angevin fortress were found.
In the southern part of Lucian Blaga Street a mortar floor with fragments of brick was discovered, probably the market mentioned by Evliya Çelebi.
