A Turret
There is a band on myspace called spire. www.myspace.com/thebandspire From South Africa
castles have around since the second century and no one knows who invented them we only know it was for defensive purposes
Cheap labor for defensive fortifications.
Showing off. Cloverleaf castles offer very little defensive capabilities apart from being stone. If the castle was made for being defensive it would have been concentric.(google it)

Spire
Not really, most castles were mainly built for defensive reasons, to dominate a particular part of the countryside and to house troops. That is not to say that there are no royal castles, there are (e.g. Windsor Castle).
A decoration on top of a gable or spire is called a finial. It is usually in the shape of a flower or a leaf.
a CASTLE ??
Fleche
Castles had strong high walls and could be used to protect the locals and hold of aggressors. they served as the central part of the community and as the place where the defensive garrisons and their weapons were kept.
Castles were built in various styles and forms throughout history, depending on the time period and region. Some common types include motte-and-bailey castles, concentric castles, and stone keep castles. Motte-and-bailey castles were early medieval fortifications consisting of a wooden or stone keep built on a raised earthwork called a motte, with an enclosed courtyard known as a bailey. Concentric castles were developed in the 12th and 13th centuries and featured multiple layers of defensive walls and towers. Stone keep castles, also known as Norman castles, were constructed primarily in the 11th and 12th centuries and featured a central stone tower or keep surrounded by walls and other structures.
