Quick visit to Siegen

Hi Everyone :)

I got invited for  my Cousin's wedding this month and would be held in Siegen, Germany.  I would really love to take this opportunity to see and explore a bit of Germany, I made some searches  online and found out that Siegen is not on the typical tourist route in Germany. Anyone,  had been in Siegen? whats your take on this? any recommendation of what to see or to do.

I thought of lingering around Cologne before I take my train back in the afternoon. Any suggestion of thing to do for 6 hours in cologne?

all comments will be highly appreciated :)
