One day I passed something unusual as I was walking down a hallway: a vault door! I discovered that over the years, this building had been used for multiple purposes. At one time, parts of it were used to store historical documents. Based on this, it would make sense that they would need a vault to protect and secure them. Instead of having the contractor remove the door when they remodeled the building, they left it in place-a great example of preserving historical elements. If you have an old door, windows, or other architectural details, trying keeping them intact to showcase the space’s history. Not only will you be preserving history, but will also have a great story to tell your guests!
