Drawbridge (Period)
A drawbridge is a type of bridge with a section of its span able to be raised or lowered. It was typically used to control access to a castle or other fortification. The drawbridge is a period charge, found in the canting arms of da Ponte, mid-15th C. [Triv 278]. By default, it’s depicted as though seen from above. See also door, gate.
