BatCat Museum & Toys

The name comes from Batman and Catwoman. The obsession, though, is overwhelmingly Batman. Owner Somchai Nitimongkolchai has been collecting since the late 1980s and, at some point, the collection, now over 50,000 pieces, stopped fitting inside a house and became, logically enough, a museum.

Spread across several cavernous rooms in the Bang Kapi, BatCat is the largest Batman collection in Asia and possibly the world. Glass cases run floor to ceiling with action figures, model cars, vintage toys, costumes, posters and memorabilia spanning the 1960s to today. Old episodes of the 1966 TV series loop on screens. There is a Batmobile sofa. Once you get past the Batman-dominated first rooms, there are also strong sections on Star Wars, Marvel, Transformers, Ultraman, Masked Rider, Toy Story and assorted manga, turning the place into a broader record of how post-war popular culture crossed the Pacific and took hold.

It is a long way out, and the traffic in Bang Kapi is reliably terrible. Plan accordingly.
