Thanks! Is it Cologne, or Köln?

Your spelling is correct in German.

Use Google: Germany. There are tourist info sites--take any one of them and find Koln, click there, and find the Dom site.

[PAR35]

Thanks! Is it Cologne, or Köln?

If you don't want to mess with the umlauts, you can also use Koeln. That spelling may be more common on the web. Here is a link to the Koelner Dom web site: http://www.koelner-dom.de/ . Click on the English flag at the top for the English language version.
