The Basilica class security bureau is an advanced structure added to more developed Romulan colonies. The purpose of which is to supervise and train security personnel. They are known to be somewhat despised by citizens of the Romulan Star Empire but they would not say this openly. This is because that, while the security officers are tasked with protecting the citizens from outside threats, they are also tasked with making sure that no sedition occurs within the colony. Its large structural frame gives it an excellent view of the colony site for this role. This also serves as a reminder to the people of their governments eternal vigilance.
