You may perhaps be interested in these two documentaries about the geometric principles that were fundamental to medieval town planning:

"Die Entdeckung der mittelalterlichen Stadtplanung" (2004): https://www.youtube.com/watch?v=-ZzEzhIGnwM

"Mittelalterliche Baukunst – Schönheit ist planbar" (2009) https://www.youtube.com/watch?v=MQcKOkbagDc

Both documentaries are in German, but are well worth watching, even if the automatic English subtitles are sometimes a little inaccurate.

Interesting! I've added them to my queue, thanks :)
