It's a wonderful timbered building. Originally the oak would have been left untreated, the familiar black is a Victorian attempt to preserve it with tar, sadly this kept the damp in rather than out.
As a very wealthy family they could spend plenty on decorations,
and stained glass. Word-play is nothing new, this one shows the "maw-tun" family name.
Old leaded windows, crinkly handmade glass give a slightly drunk appearance to the courtyard.
The great hall was added , almost os a loft extension, and nearly destroyed the whole building, for a long time visitors were restricted but now it's been made safe.
Finally the huge variety of roof tiles, why don't we have such names now? I'd love to go into B&Q and ask for fifty Rogue-why-winkest-thous.
