<human>: Mine would have to be the [House on The Rock] in Wisconsin. It is an architecturally complex house (think Frank Lloyd Wright combined with M.C. Esher) built at the top of a large sandstone formation. There are 14 buildings, each completely packed with large collections of anything and everything. 

There are collections of guns, glassware, fabergé egg  eggs, three-story bookcase filled with rare books, pianos (there had to have been 3 dozen antique pianos), organs, music machines, tobacco posters, pipes, suits of  armor, 100's of dolls, over 200 doll houses, mannequins, circus memorabilia, artifacts from the Titanic, pretty much anything you can think of, and they had it. It is like a huge museum, but it is not neat and organized, there is no rhyme or reason to the placement of the collections. 

In one room, there was a gigantic sculpture of a squid fighting a whale that was longer than the Statue of Liberty is tall. Another room had a three story carousel with 20,000 lights, 182 chandeliers and 269 
handcrafted carousel animals (none of which were horses), there were antique music machines and an 80 piece orchestra that played on it's own.

The sheer amount of stuff there was was astounding. There wasn't a bare spot on a wall. The size of the place was incredible, it took us about 3 hours tour the whole place. I can't begin to describe how much stuff there was there. The whole thing was a sensory overload and it was at times too much stimulation for my brain to comprehend. The place is a bit of a tourist trap, but it is one of the most unique place I have ever visited.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: The most interesting place I have been is a humungous house with collections of almost anything you can think of that took over 3 hours to walk through.
