The entrance to Al Hosn was through formidable doors.
The doors of Al Hosn
"The entrance to Al Hosn had a main gate called Al Derwaza in the local accent," explains Mohammed Abdullah Al Mansouri, an Emirati historian and architect.
"But there was also a smaller wooden door, made from teak that was imported from Africa or India. It was painted with shark fish oil to make it sturdy.
"The door also had several iron bolts that made it strong as well as a structure of defence.
"This door was used for visitors to enter the fort.
"They would have to bend a little, bowing their heads on entering, and this was done deliberately as a mark of respect to the building and all it represented", he said.
