The location of Lavinium has never been lost to historians nor does there appear to have been any significant break in its habitation. Today's settlement remains a walled village of medieval design, Pratica di Mare, in the "comune" of Pomezia. The latter is a city constructed in 1939 and settled according to a plan of Benito Mussolini, whose engineers completed the millennia-long task of draining and filling the marsh, now the Pontine fields. A brief strip of field separates the large and flourishing city from the village. One Roman gate allows entry into the narrow streets of the village past the Castello Borghese, originally a fortification, purchased along with the village in 1617 by Marcantonio Borghese. The castle and the village were periodically renovated. All that remains of the river that once partly surrounded the village is a small stream, the Fosso di Pratica.
