When you're actually in these old places, you notice the air just feels different - there's way more breathing room, literally and figuratively. The ventilation angle earlier folks mentioned is real, but I'd push back a bit: those ceilings weren't primarily about heat distribution from lights or staying cool in summer, since most of that benefit requires good air circulation which Victorian houses often didn't have efficiently anyway. The main reason was just plain practicality - you needed height for servants to move around carrying things, for hanging laundry indoors during winter, for accommodating tall furniture and big parties, and frankly because materials and labor were cheaper than they are now, so builders went tall without thinking twice about it. The "cooling benefit" was more of a nice side effect than the driving force.
