I grew up in a densely populated city, and there was a large 5 story building that had been converted into a stable. From the outside it just looked like a normal building, but they gutted the inside and replaced the walls and stairs with ramps so the horses could travel between floors. Every now and then, on warm days, you'd look over and see a horse sticking it's head out of a 3rd or 4th story window. It was probably jarring for a lot of people.
