The hammer-beam roof at Trunch, in Norfolk, unusual in the quality and detailing of
the tracery in the spandrils of the arch-braces. Click here for a larger, picture (150k), then use your back key to return.

(NOTE: a hammer-beam is the short beam which jetties out from the wall: half of it is hidded on top of the wall, half sticks out into open space.
The rafter joins the hidden end of the hammer beam, and the other end of the hammer beam is joined to the rafter by a vertical brace. This makes a triangle, which
stabilises the attachment to the top of the wall, and strengthens the lower part of the rafter. The hammer is triangulated against the wall with an arched brace,
so that the sideways pressure of the roof to spread is taken against the face of the wall, not just by the top of the wall.)
