Please take look at the followoing paragraph from a textbook.
During the Middle Ages, most castles were built in the shape of a square. They had a large tower in each corner. These towers were usually made of stone. A thick stone wall ran from tower to tower and formed an area called the inner ward. A large central tower was called the keep. This was always the strongest part of the castle. The lord and his family lived on the upper floors of the keep. The soldiers lived on the lower levels. The keep had many secret rooms and getaway passages. It was here, in the keep, that all the village people would hide during times of great danger. There were many underground tunnels leading to the keep. The other towers were used for the prison. The great hall was the place used for town meetings. The kitchen and bake shop were also part of the castle.
What is It indicating? and What is that indicating?

I am beginning to understand how to use a relative adverb.

Would it be possible to replace that with where?
It was here, in the keep, where all the village people would hide during times of great danger.

I found another grammatical item in my grammar book.
It is .... that sentence structure.
The following is example sentences from the grammar book.
#1 It is he that (or who) is to blame.
#2 It is not the expense I'm worried about. (that can be omitted)
#3 It is this hot weather that (or which) makes he irritable.
#4 It was difficult that he solved the problem.
#5 It is chiefly through books that we get knowledge.
#6 It was what he said that worried me.
#7 It is not until (or only after) you lose your health that you realize its value.
The original in the keep sentence can be considered the same as above?
