Detected a German WWII airfield this week.  Has been in operation for over 75 years, taken over by the German military during WWII and reverted back to a small civilian airfield.  I stopped by the club house to inform them what I would be doing and they got a little defensive and said no I can not detect here.  After explaining that it is city owned, my tax dollars paying for it and the fact I have a legal permit to detect it he agreed but only after thoroughly reading my permit.  He said please do not dig on the runway, I laughed and promised I would not dig holes in his runway and I only wanted to detect around the old WWII buildings.  He was very helpful afterwards, pointed out the only building built by the military and also showed me some pre WWII photos of the airfield.  I was also invited to a flight in a motorized glider so I can take aerial photos of the land, for about $30.00, LOL.  The right part of the building in the photo was the only building from WWII, the barn portion is a add on.

Detected around the building for about 1.5 hours, found a lot of junk, a few brass ammo casings and this nice little pendant.  It is a religious pendant from a Cathedral in Trier.  A coat of arms with a crown surrounded by the legend reads "Der Heilige Rock Im Dom Zu Trier" or "The Holiness Lays In The Cathedral of Trier" is the best I can translate.  I estimate the age to be around the late 1800s.

Reverse of the pendant.  In the middle is the Cathedral with a legend I have not tried to translate yet.  I thought this was the Roman Porta Nigra "Black Gate" in Trier built around 150 AD, it was converted into a church around 1024 AD.

The Porta Nigra "Black Gate" in Trier.  It was a Roman super structure in its day.  Napoleon ordered the church dissolved around 1804 and the Roman Gate reverted back to its originality.

This is the Trier cathedral and is probably the building on the pendant.  HH, Mike
