The earliest known Latium was the country of the Latini, a tribe whose recognised center was a large, dormant volcano, Mons Albanus (the Alban Mount, today's Colli Albani), to the southeast of Rome, in circumference. In its center is a crater lake, Lacus Albanus (Lago Albano), oval in shape, a few km long and wide. At the top of the second-highest peak (Monte Cavo) was a temple to Jupiter Latiaris, where the Latini held state functions before their subjection to Rome, and the Romans subsequently held religious and state ceremonies. The last pagan temple to be built stood until the Middle Ages when its stone and location were reused for various monasteries and finally a hotel. During World War II, the Wehrmacht turned it into a radio station, which was captured after an infantry battle by American troops in 1944, and it currently is a controversial telecommunications station surrounded by antennae considered unsightly by the population within view.
