Both churches have towers that remind the viewer of the heavens while pointing to the sky. The church in Cologne is quite a bit taller (although narrower). Our group discussed that one reason for this was because of it's location at the center of town, it needed to make a statement. The height of the church, however, came at a cost. The building is very narrow because the architects at the time didn't have the technology or understanding as to how to make the building wider at the height they desired without it collapsing upon itself.
Built later than the cathedral at Cologne, the cathedral at salisbury was able to achieve significant height, width, and depth.
The effect from the inside gives the impression that it really is massive and impressesive, truly built on a grand enough scale to be a house of God.
When comparing the location of the two churches, one can speculate about the reasons for some of their architectural and design elements. Cologne's cathedral is located in the center of two, on the center axis of two main roads. I believe the reason that there are two towers is because visually and physically, one could draw a line right down the center of the main road and end up through the entrance and inside the church.
Salisbury, though located in a bustling urban center, is surrounded by a grassy knoll. A small side street is barely detectable. It only has 1 tower, which marks the center of it's location. It says "hey, come check me out" instead of "you must walk through me to get to the other side.
In order to remember the churches and their differences, I used an adapted version of symbols we learned in class.
Cologne: ^ + ^
This reminds me that there are 2 tall towers and the church falls at the center of an axis.
The circle with an arrow head tells me that the church is at the center of an open area and only has 1 tower.
