A Hauted House is a ride often found at fair-grounds and amusement parks. Depending on how up-market the fair is they can be fairly creepy, or funny, but more often are very boring.
The construct is always almost exactly the same. It is a large-ish building made to look like a haunted house, or Dracula’s castle, or something on the same theme. At the front is a railway-like-track with about four or five cars on it, sometimes shaped to look like a train, usually not.
The cars then begin to move, the move through a door to the left or right, which is usually themed to look like a portcullis or something similar. Once in it is completely dark. Suddenly a fluorescent light lit model of a ghost may come into view, maybe flying over the top of the cars, possibly a vampire will spring out of his coffin, or a spider will drop down in front of the cars. Depending on the ride these can be cartoonist and funny, or realistic and creepy.
The car may go up or down gentle or not so gentle slopes, still with paranormal models over-head and to either side. Finally it will emerge into the outside world again, where, if you duck you might get a free go, if not, you can get out and go over to the waltzers.
