Inheriting something from a distant relative always ends in a surprise. After the passing of her great aunt, this German woman inherited her old house.

Inside, she discovered a heavy safe, and after popping it open and taking a look, she knew nothing would ever be the same.

The safe was found shortly after arriving at the house, so they immediately went to work getting it open.

The woman’s great aunt had fled Russia in the 1940s and settled in Hamburg, Germany.

After some time, they found a mysterious key.

Sure enough, it worked…

What they found inside was deeply intriguing.

Imgur

There were letters, books, and pictures, but something seemed off.

One of the books was a copy of Adolf Hitler’s Mein Kampf.

Imgur

This edition was published in 1943, well after the infamous dictator’s rise to power.

Imgur

Its estimated worth is around $350.

There was also a copy of Rob Roy by W. Scott.

Imgur

Published in 1846, there’s no telling how valuable it is.

This very old copy of Lady and the Tramp was inside, too.

Imgur

It’s also in German, making it an even more exceptional find.

The girl here is likely her great aunt as a little child.

And this is her grandfather in 1950.

These boys were in the Hitler Youth. These pictures must have given her mixed feelings.

This German postcard is from 1916, right in the middle of World War I.

Here’s one from 1941 with a stamp from the Nazi government.

And another from 1916 showing a nurse and a soldier.

This picture’s caption reads, “A house destroyed by the enemy.”

Some of these brands, like Nivea, you might recognize from today.

This photo shows the heir to the Kaisers during World War I.

This safe held a piece of history from a truly dark time. Though the woman said that many of these items were common to own at the time, it’s still incredibly eerie to see all these years later.
