The History Of All Saints' Wickhambrook
Hammerbeam Roofs
Hammerbeam roofs are an ingenious invention of English building
and first made their appearance in East Anglia in the late 15th
century. It is can almost be thought of looking down into the structural
interior of a wooden ship - and could be that carpenters schooled
in shipbuilding were involved in its inception. The key discovery
that made the new roofs possible was that the central section of
a crossbeam supporting higher roof timbers could be removed, leaving
the weight sufficiently supported on the remaining ends, or hammers.
The force is transferred to the walls, on occasional by two levels
of hammerbeams (however in most instances of a double hammerbeam,
the upper series of hammers are purely decorative. From the original
invention glorious exuberant structures can be seen quite often
adorned with spread-winged wooden angels on the end of the hammers.
The finest example of a hambberbeam roof is the one formed over
Westminster Hall, London.
