The St.Peter and Paul church in Remagen by globetrott
The St.Peter and Paul church in Remagen dates back to the year 1246 and was restored and made larger in the year 1900. It looks great at some places outside with lovely romanic ornaments around the side-entrance, but unfortunately I did not see the interior, as they had church-service at the time I was there.
In one of the side-chapels you may see frescos dating back to the 12th century.
