To find the 10 weirdest museums worth going out of your way for, Accor scored 50 museum experiences across Europe on six criteria: theme rarity, concept oddity, social virality, visitor ratings, ticket price, and travel time. 

Here are Europe’s Top 10 Weirdest Museums: 

  1. Zagreb: Museum of Broken Relationships 
    A heartbreak archive unlike anything else in Europe, displaying everyday objects – a toaster, a bicycle lock, a pair of shoes, donated by strangers following the end of a relationship, each with a short, anonymous note. Equal parts funny and devastating. 
  2. Prague: Museum of Alchemy 
    Discovered by accident after a flood uncovered a hidden basement network, this underground museum reconstructs the workshops of historical alchemists with unsettling atmospheric precision. Think low ceilings, dim lighting, and clay ovens once used to chase the dream of synthesising gold. 
  3. Rome: Museum of the Holy Souls in Purgatory 
    Free to enter and tucked inside a church sacristy in Prati, this tiny archive displays objects said to bear the physical marks of souls communicating from beyond, arguably the most unsettling free museum in Europe. 
  4. Edinburgh: Museum of Magic, Fortune-telling & Witchcraft 
    Scotland executed more people for witchcraft per capita than any other European country, and this collection brings that history to life through protective charms, folklore objects and centuries-old occult paraphernalia. 
  5. Berlin: German Spy Museum 
    A highly interactive dive into Cold War espionage, packed with surveillance equipment, forged documents and classified-era gadgetry, the most socially viral entry on the list by a wide margin. 
  6. London: Viktor Wynd Museum of Curiosities 
    A cabinet of curiosities rebuilt for the 21st century in East London, where natural history specimens sit alongside literary oddities, taxidermy and fine art, with no labels and no obvious logic. 
  7. Barcelona: Museum of Funeral Carriages 
    Located within Montjuïc Cemetery, this is the only public display of its kind in Europe – ornate 18th and 19th-century horse-drawn hearses decorated with carved owls and baroque ironwork. 
  8. Amsterdam: Cat Cabinet 
    Hidden inside one of Amsterdam’s grandest canal houses, an entire museum dedicated to cats in art and culture, founded by an eccentric collector in memory of his own beloved cat. 
  9. Paris: Sewer Museum 
    Beneath Haussmann’s boulevards, this museum traces the full history of the French capital’s underground infrastructure, from Roman drainage channels to the vast modern network, and it smells exactly like you’d expect. 
  10. Brussels: Frietmuseum 
    An entire museum dedicated to the Belgian chip stand, tracing the fritkot’s architectural and culinary evolution over more than a century with the seriousness of a national gallery.
