Concentric castles were the next follow on from stone keep castles. Concentric castles, in Britain, are most associated with Edward I and North-West Wales where a series of huge castles were built. The most famous concentric castles are at Harlech, Beaumaris, Caernarvon and Conway.
Unlike square keep castles, concentric castles had no central keep. In many senses, they had no centre either as all parts of the castle would have been considered to be a strong point. Each concentric castle had a very heavily defended entrance and the central core was defended by a series of curtain walls. The furthest of the curtain walls would have been the smallest in height to allow the defenders to see an approaching enemy. The curtain wall nearest to the castle would have been the highest to give the defenders the maximum height advantage over those attempting to take over the castle.

What else can I help you with?
Does a higher number of conducitvity mean is conductive?
Yes, the higher the conductivity concentration the higher the conductivity value in the material. Some times the conductive particles are surrounded with insulating materials which cut the conductive paths between the electrodes and as a result it stops the increase in the conductivity values to a certain limit according to the structure (texture) in the material.
Does an increase in the number of ions result in higher conductivity?
Yes, an increase in the number of ions typically results in higher conductivity.
What material has the higher electrical conductivity?
The highest degree of electrical conductivity is in silver.
What are conductivity metals?
Metals have a higher electrical and thermal conductivity than nonmetals.
How does the conductivity of graphene compare to that of silver?
Graphene has higher conductivity than silver.
When the thermal conductivty is higher what is it mean?
When thermal conductivity is higher, it means that the material is better at conducting heat. This means that heat transfers more easily through the material, making it a better conductor of heat compared to a material with lower thermal conductivity.
What is higher 5.8e7 or 9.5e5 conductivity of metals?
5.8e7 is a larger number than 9.5e5. 5.8e7 can be written as 58,000,000, and 9.5e5 can be written as 950,000. Conductivity is a measure of the ability of a material to conduct electricity. A large conductivity means that the material conducts electricity well. The units of electrical conductivity are siemens per meter (Sm-1).
What does a higher thermal conductivity indicate about a material's ability to transfer heat?
A higher thermal conductivity indicates that a material is better at transferring heat.
What does thermal and electrical conductivity mean?
Thermal conductivity refers to a material's ability to conduct heat, with higher conductivity indicating faster heat transfer. Electrical conductivity, on the other hand, refers to a material's ability to conduct electricity, with higher conductivity allowing better flow of electrical current. Both properties are important in various applications, such as in designing efficient cooling systems or conducting electricity in electronic devices.
What is soil conductivity?
Soil conductivity is a measure of a soil's ability to conduct an electrical current. It is influenced by factors such as soil moisture content, soil texture, and the presence of salts and minerals. Higher soil conductivity levels can indicate higher levels of salinity, which can impact plant growth.
What is the relationship between conductivity and salinity in water?
The relationship between conductivity and salinity in water is that conductivity increases as salinity increases. Salinity refers to the concentration of dissolved salts in water, which can conduct electricity. Therefore, higher salinity levels result in higher conductivity levels in water.
The ability of a solution to conduct an electrical current is its?
conductivity. It is a measure of how well a solution allows the flow of electrical current through it. Solutions with higher concentrations of ions or charged particles tend to have higher conductivity.
