I am postponing the map with a day or two, but here is a rough description.
The middle part of the chapel is approximately 100ft in diameter and the monk is now in the middle of this circle. There are three doors out, main door, the one you used and the the one connecting the graveyard to the church.
In addition to these doors there are five more in the bottom floor of the church. Four of these are positioned in 90 degree angle with each other along the perimeter of the chapel. The fifth one is the one the priests use to walk to the speaker's stand.
The chapel seems to go all the way up the church, but it is clear that there are rooms around it on all levels. So technically the church is like two circles, the smaller of which is inside the larger one. The smaller circle is as high as the church and is open, while the larger circle has several, probably seven or eight floors.
Did that make any sense?
