If you are a WWII history enthusiast like me, than you will probably want to visit museums and historical sites related to the war if you are ever in Germany.  Here is a list of locations I recommend.

Laboe - Home of U-995, a type VII U-Boat that is restored and open to public viewing.  It is located next to the Naval War Memorial.  A walk through the submarine will really give you a feeling for the cramped quarter the sailors had to endure during their tour at sea. 

Laboe - Marine Memorial and Museum.  Located next to the U-995, this memorial was built to honor the fallen sailors of all wars.  It has a fantastic view from the top of the memorial, and many interesting srtifacts and displays on the property and in the halls.

Heikendorf - U-Boat Memorial.  No matter what country you are from, this memorial is a very somber reminder of the cost of war.  The memorial walls are lined with plaques listing the names of thousands of men lost at sea during the war.

Hamburg - Flak Towers.  Two flak towers (Flakturm) remain in the city.  They are not museums or open to the public, but they are an awesome site to see if you are in the area.

Munster - Panzer Museum.  This is a must-visit location for any WWII armor enthusiast.  Besides the many examples of tanks and other armored vehicles, you will also see Rommel's uniform and death mask as well as the Fieldmarshall Baton of Günter von Kluge.

Berlin - One of many famous sites in the city is the Brandenburg Gate.  Just inside the gate is the Hotel Adlon, a favorite spot of many high ranking German officials during the war.  The original hotel was destroyed at the end of the war, but it has been rebuilt to the original plans (almost).

Berlin - The Reichstag, one of the most famous and important sites in the city.  It's destruction by fire before the war was a warning of things to come, and the placement of the Soviet flag on it's roof by a conquering soldier in 1945 helped signal the end.  It has been rebuilt and there are tours available to it's dome.

Berlin - Flak Tower III (Flakturm III) at Humboldthain.  This is one of three original Flak towers in Berlin, and the only one where a substantial part of it remains (G Tower).  You get a nice view of the city from the gun placements at the top of the tower, but you can also take a guided tour within the structure.

Remagen - The famous bridge into Germany that the allies were able to capture before the Germans could destroy it.  The bridge itself collapsed in 1945, but the entrance towers remain and a small but interesting museum is on the property.  I recommend watching the movie before you visit.

Koblenz - WWII Technical Museum.  Packed full of Tanks, cannons, weapons, equipment, and many other artifacts from WWII.  Located in an old Tank taining base, it is definately a place to visit if you are in the area.

Sinsheim - Auto & Technik Museum.  I have not been to this museum, but I have heard it has some pretty good WWII vehicles and artifacts on display.  They also have a smaller one in Speyer.

Herrlingen - Rommel Archiv and gravesite.  A small archiv/museum within walking distance of Rommel's final resting place.  It is a single room of photos, documents, and a few artifacts run by the local chamber of commerce, I recommend calling before you visit.

Herrlingen - Rommel memorial at the site where he was forced to commit suicide by poison.  This open area just off the road is about a mile from the home he and his family were living in at the time of his arrest.

Nuremberg (Nürnberg) - Luitpold Arena and Congress Hall.  The arena was the site of the early Nazi party rallies that is seen in so much WWII footage.  The Congress Hall was a grand architectural plan that was never completed.  It now houses a documentation center (museum).

Nuremberg (Nürnberg) - Zeppelin Field and Great Road.  The field was a more permanent structure or arena build to house the late Nazi Party rallies.  The podium from where the Fuhrer made his speaches still remains.  The Great Road was another grand architectural plan that was never completed due to war.

Nuremberg (Nürnberg) - The Old Salt City.  One of the most beautiful and historic German cities I have been to.  The old town area has so much history from before WWII, but it was also the site of many 3rd Reich parades and is seen in a lot of war era footage.

Nuremberg (Nürnberg) - The Palace of Justice.  Location of the famous Nuremberg Trials for the war criminals of the 3rd Reich.  Tours of the famous courtroom 600 are available.

Munich - Birthplace of the Nazi party.  This is a beautiful city with many 3rd Reich points of interest.  The Feldherrnhalle was the site of many a Nazi rally, but it was also next to this monument that Hitler's failed putsch in 1923 ended in bloodshed. 

Berchtesgaden - The mountain resort that became the vacation spot for top Nazi's.  This Bavarian Mountain Resort town is just down the hill from the Obersalzberg area where many top Nazi's had their homes.  It was also liberated by the 101st Airborne, so it has history related to the main subject of this website as well.

The Obersalzberg - Literally home of the Nazi's.  This mountain resort area contained homes for top Nazi leaders like Hermann Göring, Martin Bormann, Albert Speer, and of course Adolph Hitler himself.  It also had the SS barracks and many other Nazi structures in this area. 

Obersalzberg - Hotel Zum Türken (Tuerken).  Seized from it's original owners by the Nazi's, is is now owned by the daughter of those owners.  The building is next to the former site of the Berghof (Hitler's house) and was used as barracks by the SS and SD senior officials.  It is a great place to stay on the mountain and has an interesting bunker system below that is open to the public.

Obersalzberg - The Kelsteinhaus, or better known as The Eagles Nest, sits on a peak high above the Nazi complex and homes of the area.  Built as a birthday present for the Fuher by the Nazi's, it was rarely used.  Bus tickets can be purchased to take you mid-way up the mountain where an elevator will take you to the top.  On a rare clear day the view is fantastic.
