A museum might not be at the top of your vacation to-do list, but if you’re visiting some of Europe’s major cities, there are a few fascinating and downright strange museums that you might want to visit.

Amsterdam is renowned for its red light district, but it is also home to its own sex museum packed with an interesting array of art, figures, china, photos, and other items that are dedicated to human sexuality. Entry is only available to those over the age of 16.

If you’re choosing one of the vacation rentals in Berlin, you should pay a visit to the Designpanoptikum. The Museum of Extraordinary Objects is a collection of weird medical and industrial objects, some of which have been cobbled together to create new and even stranger contraptions.

The Museum of Caricature in Warsaw was founded by a Polish cartoonist, satirist, and journalist. Although it is a very small museum, it’s filled with more than 20,000 different pieces of work from across the globe.

The Capitoline Museums in Rome might not sound that intriguing, but the extraordinary mix of the modern and classical worlds found here is far from boring. The first public electricity site in the city now houses Roman and Greek sculptures, which sit amongst the engines, boilers, and turbines.

Amsterdam’s Museum of Bags and Purses is a popular site for female travelers. This private collection has exhibits from the last 500 years, including bags, suitcases, purses, and pouches.
