Work executed with more or less large stones put together without any attempt at courses is called rubble][ walling. Where similar work is laid in courses, it is known as coursed rubble. ]Dry-stone wall
Dry stone, sometimes called drystack or, in Scotland, drystane, is a building method by which structures are constructed from Rock (geology), stones without any Mortar (masonry), mortar to bind them together. A certain amount of binding is obtai ...
ing is somewhat similar work done without the use of mortar. It is bound together by the fit of the stones and the regular placement of stones which extend through the thickness of the wall. A rubble wall built with mortar will be stronger if assembled in this way.
Rubble walls in Malta
Rubble walls () are found all over the island of Malta
Malta, officially the Republic of Malta, is an island country in Southern Europe located in the Mediterranean Sea, between Sicily and North Africa. It consists of an archipelago south of Italy, east of Tunisia, and north of Libya. The two ...
. Similar walls are also frequently found in Sicily and the Arab countries. The various shapes and sizes of the stones used to build these walls look like stones that were found in the area lying on the ground or in the soil. It is most probable that the practice of building these walls around the field was inspired by the Arabs during their rule in Malta, as in Sicily which was also ruled by the Arabs around the same period. Maltese farmers found that the methods of building these walls was very efficient especially when resources were limited. Rubble walls are used to serve as borders between farms. A great advantage that rubble walls offered is that when heavy rain falls, their structure would allow excessive water to pass through and therefore, excess water will not ruin the products. Soil erosion is minimised as the wall structure allows the water to pass through but it traps the soil and prevents it from being carried away from the field. One can see many rubble walls on the side of the hills and in valleys where the land slopes down and consequently the soil is in greater danger of being carried away.
