Whether you are arriving or leaving Normandy this batterie and museum is very easy to find.
If you are coming from the west and are leaving then you will take the D514 motorway (highway). If you are coming from the east you will take the D27 to the D513 to the D95A which leads into the D223.
The town of Merville is rather small and when driving through from any direction it will head towards the street called Avenue de la Batterie de Merville which takes you straight to the site. If you are coming directly from the west then the street intersects before hand and that street name is Rue Colonel Otway.
If you are coming into Normandy from the north easterly direction you will be taking the D514 to the D223 and you will eventually pass through the small town of Descanneville. After going through the town you will take a right on the Avenue Alexandre de Lavergne, drive a short distance and take a left on the Avenue de la Batterie Merville, the batterie and parking is straight ahead.
The parking is limited so get there early if you can. There is a nice gift shop on the premises and the entry fee is minimal.
Another German batterie that saw fierce fighting on D-Day. The Merville batterie was attacked the night before the landings or the early hours of by the British Parachute regiment, 9th battalion and was commanded by Lieutenant Colonel Terrance Otway. The attacking forces suffered heavy casualties but the batterie was eventually taken.
This museum features a really interesting visual and audio display in a type theater mode inside one of the bunkers. I was able to video tape it on my GoPro camera and will upload it here as soon as I have the time.
I used two different cameras on the 2016 visit. The Nikon Coolpix 35mm and the Apple iPhone Six Plus.
