Some soffit panels (located under the eaves).
If you do not have soffit vents, like me, only a minimal air flow will be felt.
The cracked door-lintel, which shows an eagle on the soffit, was propped up first by Burton, and lately, more securely, by the Germans.
In architecture, the term "corona" is used of that part of a cornice which projects over the bed mould and constitutes the chief protection to the wall from rain; it is always throated, and its soffit rises towards the wall.
Strengthening the soffit using stainless steel reinforcement gave a significant increase in the load carrying capacity.
