ancient city, ancient gate

Torun is a city on the Vistula River.  It is one of Poland's oldest cities, first settled in the 8th century, and has been a world heritage site since 1997.  According to the sender, it is renowned for its gingerbread which has been made there for over 1,000 years.

The Porta Nigra in Trier, Germany is even older, having been built as a Roman Gate around 170A.D.  No one knows what the Romans called it, but it has been called 'nigra', or 'black', since the middle ages, when the original grey sandstone became darkened.   It is the only one of four city gates remaining and was designated a world heritage site in 1986.
