During archaeological excavations and architectural research carried out on the structure before the reconstruction works

started, many interesting finds were made. It was confirmed that its northern part located on more solid ground is, in spite of being blown up, better preserved than its southern part. This finding lends credence to a possible construction disaster of this bastion and its makeshift reconstruction in the 17th century. In the northern flank of the bastion relics of a huge, two-part casemate have been discovered; it dates back to the remodelling carried out by Mallet. Apart from that a postern – a corridor which leads to it has also been found. However, traces of a walled-up corridor and an older, Polish casemate from the 17th century have also been found. These valuable finds have been preserved and displayed in a roofed archaeological reserve, at the entrance of which you are standing. Another very interesting find was a fragment of a face corner of the bastion which shows that the bastion had changed its colour. After the last remodelling it was plastered light grey and faced with artificial, masonry-like white bossage. It changes our belief that the whole Zamość fortress was built from red brick. At the final stage, in the middle of the 19th century, Bastion III and probably also other fragments of the fortress were light grey.
