Nowadays, the ruins of the ancient Prefecture can be seen at the important archaeological site nearby the village. The town was given the name Prata because of the huge lawns found in the area.
The thirteenth-century parish church of St. Nicholas of Bari, is on the edge of the Peltuinum archaeological site. This church guards a valuable pulpit from the year 1240 belonging to the picturesque church of St. Paul of Peltuinum. A few kilometers from the remains of the Roman city is the spectacular walled medieval town of Castelcamponeschi (or Castle of Prata), built around the twelfth century.
