Answer 2

A part of wall coming out in round shape it is built to ensure security is Bastion.

Explanation:

• Bastion is the term given to a section of the fort wall that ejects in a round shape (Burj). These were thick defended walls that looked outward, securing the fort's security.

• As a function, the shape was designed to maximize the performance of enfilade ( angling) fire against any attackers who finally reached the base of any of the walls.

• By around 1450, the first bastions appeared in Italy as modified towers with a spreading, wounded foundation, lower in elevation than the typical ancient tower.

• Early bastions, including those at Corinaldo and Morro d'Alba in the Marches, tended to be circular in shape.

• The fort's defensive structure consists of temples and water tanks
