Historic Sights?

Backblip:

Today's meetings were slightly less intense than yesterdays and this evenings meal was with a larger group of colleagues than last nights so I thought it may be a little more relaxing (and it was). The meal was in the centre of Koln so I was looking forward to a brief walk through the historic centre to get to the meal. Unfortunately this was not to be...the restaurant was in a modern centre of buildings and not a historic building in sight...oh well.
