A watchtower, alternatively called a sentry tower, was essentially a pod that was raised either by a repulsorlift platform or fixed upon a physical stalk. A sentry would be positioned on it to maintain a lookout for any threats that might be coming. During the Clone Wars, the Confederacy of Independent Systems employed multiple watchtowers in the capital city of Iziz on the planet Onderon. Furthermore, the Alliance to Restore the Republic built a number of these towers at the Massassi Site on Yavin 4 for use by Rebel sentries. Some years after this, the Resistance installed a watchtower at their base within the Ancient ruins close to Black Spire Outpost which was located on Batuu.
