Turan refers to a series of signaling towers that were prevalent along the Istria coast. These towers, originating in the Roman Empire era and extensively utilized during the Venice Republic's rule, were dedicated to enabling communication networks. Using fires at night and smoke signals during daylight hours, they transmitted messages to other towers within their visual range. Essentially, Turan towers were pivotal in facilitating communication among themselves and with vessels navigating the coast during the night. Placed strategically in a network configuration, each tower had a clear line of sight and communication with neighboring towers, establishing an interconnected system intended to improve visibility and messaging efficiency.
