Repairing a monument that is also a main road
Chanioporta is one of the three monumental gates of the Venetian fortifications of Heraklion, alongside the Jesus Gate and the Gate of St George. By the early twentieth century the city had outgrown them — the gates were too narrow for carriages, so sections of wall were demolished where the main roads ran out to the countryside.
Of all the breaches cut through the walls, only three were ever bridged. The first was Chanioporta, in 1915: an opening fifteen metres wide, spanned by a broad stone arch. That arch is what carries the traffic today, between the historic centre and the western suburbs.
A century on, the inside of it was failing. Severe damp, water running through the vault, transverse cracks, and binding mortar that had turned to dust. The work was to stabilise and restore it without altering the architecture of the monument — and without stopping the traffic that made it necessary in the first place.

Traffic, then a temporary frame
Chanioporta is not a monument you can close: it carries a main artery between the historic centre and the western suburbs. Traffic was managed around the works, and a steel structure took the load of the opening so nothing could settle while the arch was opened up.
Grouting the vault
Inside the arch the mortar had disintegrated and water was running through. Grout was injected to fill the voids and homogenise the mass of the vault, and the cracks in the wing wall and the interior were repaired.
Replacing stone
Eroded and broken stones were cut out and replaced with new ones, selected to match, and fixed with stainless-steel dowels. Then the joints were repointed across the face.
Keeping the water out
The cause, not the symptom: the fill above the vault was waterproofed with an industrial floor, the parapet stones restored, and the walkway over the arch re-formed so it is safe to cross.
