Walls revisited

Thread from the old ATU site:

I suppose I'd better preserve a few of these cached images from the old ATU site before the link expires:


Great Wall of China.

Western (or "Wailing") Wall, Jerusalem.

Berlin Wall.

The caption to this one says:

"The monument is located along a path leading from the south parking lot to the southwest entrance
of the original CIA Headquarters building at the George Bush Center for Intelligence.

It was dedicated on December 18th, 1992."

Fragment of the London Wall at Cooper's Row, originally built by Roman colonists to exclude marauding Brits.

Queen Boudicca of the Iceni tribe had burned the city to the ground.

Dig into the London clay today and you'll still find a stratum of ash.

The square mile delineated by the old Roman wall now houses the City of London: the financial district.

Walls of Jericho- speculative reconstruction from archaeological evidence.


What's left of them.

Section of Hadrian's Wall, constructed by the Romans to keep out the barbarian Picts and Scots.

The term "Wooden Walls" to describe a country's navy is thought by some to be peculiarly English.
However, we find it used at least once in an earlier civilisation.
The Delphic oracle, on the subject of the Persian invasion of Athens says:

"Defend yourselves by wooden walls".

Curtain wall of the crusader castle Krak des Chevaliers, Syria.

A curtain wall is a defensive wall between two bastions of a castle or fortress.

In earlier designs of castle the curtain walls were often built to a considerable height and were fronted by a ditch or moat to make assault difficult.

Later with the introduction of trace italienne fortifications the height of the curtain walls was reduced and beyond the ditch additional outworks such as ravelins and tenailles were added to protect the curtain walls from direct cannonading.

Ruins of a Han Dynasty watchtower made of rammed earth.

Wiki:

Rammed earth, also known as taipa (Portuguese), tapial (Spanish), pisé de terre or simply pisé (French), is a technique used in the building of walls using the raw materials of earth, chalk, lime and gravel. It is an ancient building method that has seen a revival in recent years as people seek more sustainable building materials and natural building methods. Rammed earth walls are simple to construct, incombustible, thermally massive, very strong and hardwearing. Conversely they can be labour-intensive to construct without machinery (powered rammers), and if improperly protected or maintained they are susceptible to water damage. Traditionally, rammed earth buildings are found on every continent except Antarctica. From temperate and wet regions of north Europe to semi dry deserts, mountain areas and the tropics. The availability of useful soil and building design for the local climatic conditions are the factors which favour its use.

An early wall-building technique involved the "wattle and daub" method:


A wattle framework.

Wiki:

Wattle and daub (or wattle-and-daub) is a building material used for making walls, in which a woven lattice of wooden strips called wattle is daubed with a sticky material usually made of some combination of wet soil, clay, sand, animal dung and straw. Wattle and daub has been used for at least 6,000 years, and is still an important construction material in many parts of the world. Many historic buildings include wattle and daub construction, and the technique is becoming popular again in more developed areas as a low-impact sustainable building technique.

...but "wattle and daub" structures could also become quite elaborate:
