The surrounding wall of the monastery forms a nearly rectangular quadrangle and surrounds an area of 5200 m².
The feeling of a fortress is reinforced by the embrasures that are on the top part of the west wall and on the southern and eastern façades.
Additionally, the width of the outside eastern wall is 1.20 meters.

Inside the walls are buildings such as the hegumen's house, the monks' cells, the refectory, the stockrooms, the powder magazine and the hospice.

The monastery has two main doors : one to the west and one on the east of the building.
Entree could also be made through smaller doors: one in the south-west, two to the north and one last on the western façade.

The main door of the monastery is on the western façade of the surrounding wall.
This door is called Rethemniotiki or Haniotiki, after its orientation towards those two towns.
The original door was built in 1693, by the hegumen Neophytos Drossas.
A manuscript at the monastery describes the original door, which was destroyed in 1866 during the Turkish assault.
Made of square stones, there were two windows, decorated with pyramid-shaped pediments and framed by ribbed columns that were decorated with lions.
On the pediment, there was an inscription that read:
"Lord, watch over the spirit of your servant, the Hegumen Neophytos Drossas, and of all our Christian brothers."

The current door was built in 1870.
The general form of the former door was conserved, with two windows at level, framed by two columns.
But the inscription honoring the hegumen Drossas, the lions and the pediments were not rebuilt.

On the eastern façade of the wall is the second door to the monastery.
Facing Heraklion, the door is named Kastrini, after Kastro.
As with the western door, the original door was destroyed in 1866 and was rebuilt in 1870.
