According to Philo the width of a wall had to be 4.5 metres (15 ft) thick to be able to withstand ancient (non-gunpowder) siege engines. [16] European walls of the 1200s and 1300s could reach the Roman equivalents but rarely exceeded them in length, width, and height, remaining around 2 metres (6 ft 7 in) thick.
A guideline used in this zone can be "low, lean and green." Trees should be kept to a minimum of 10 feet (3 m) from other trees to reduce risk of fire spread between trees. Wood piles should be kept in zone 2. No branches should be touching or hanging over the roof of the house or within 10 feet of the structure to help keep the structure safe.
The walls exposed to enemy fire are almost 12 meters (39 feet) thick, but the large wall surface facing the city does not exceed 60 centimetres (2 feet). Two drawbridges lead to the fort, there being the inscription "Non Bene Pro Toto Libertas Venditur Auro" – "Freedom is not to be sold for all the treasures in the world."
In the construction of masonry buildings, a fire cut [1] or fireman's cut is a diagonal chamfer of the end of a joist or beam where it enters a masonry wall.
