The room just beneath the battlements is a tiny circular chamber, accessed by a thick timber door from the terrace, positioned beneath the steep little iron stair that takes you up onto the battlement proper. The room contained a writing desk and a chair, and it had small lead-lined windows looking out and down to the River. I opened one, and saw some boats steaming along in the current many hundreds of feet below. The room felt suspended in mid air, between heaven and earth, and its austerity and simplicity impressed themselves upon me. Apparently Kaiser Wilhelm II had used that very room to write in, and while he is not my favourite historical personage I cannot fault his taste in 'perches' for writing. Overlooking the Rhine placed the room on one of the principal arteries of industry and trade, and one of the signature natural features of Germany. The castle behind provided a psychological security, and yet the room itself was tiny.
Basically, I want one.
