Lazio is not just Roma caput mundi (Rome capital of the world) and the Vatican City. On the plain towards the south is Latina, a fine example of rationalist architecture, while in the other direction is Viterbo with its Papal Palace. Travelling inland to Sabina, on the slopes of Mount Terminillo is Rieti! Then going on to Ciociaria, there is Frosinone, a surprisingly modern city despite its a medieval layout, near to which is the most symbolic place in Lazio: Montecassino Abbey.
