Spanning solutions for apertures in traditional architecture in Malta [2, 40, 42]

Span (s)	Spanning solutions
s ≤ 0.9 m	Masonry lintel
0.9 m < s ≤ 1.1 m	Relieving arch Notching of dimension stone exactly above lintel Depth of lintel increased to 1.5 times the depth of a masonry lintel for a 0.9 m span
s > 1.1 m	Masonry arch
