Gungan Temple
From Wookieepedia, the Star Wars wiki.
The Gungan Temples were sizable structures that held special meaning to the Gungans. They were used to hold sacred staffs in Spinnaker three millennia prior to the Battle of Yavin. Boss Nass would later use one as a rallying point for the Gungan Grand Army after the liberation of Harte Secur during the Invasion of Naboo in 32 BBY. Gungan Temples required considerable amounts of ore, nova crystals, and carbon to construct.
