Quadrilatero Romano and Porta Palatina

The Quadrilatero Romano is the oldest part of Turin, Piedmont, a compact grid of lanes laid out in the Roman period on the site of the colony of Augusta Taurinorum. Its anchor is Porta Palatina, a 1st-century Roman gate on Piazza Cesare Augusto, one of the best-preserved Roman gates in northern Italy. Two brick towers with sixteen-sided shapes flank the passage, and the remains of the adjacent theatre can be seen in the archaeological area behind it, which has seasonal opening and may charge for guided entry. The gate itself can be viewed from outside at any time and is free. Around it, the neighbourhood has medieval and Baroque layers, narrow streets, small shops, craft studios and a dense mix of bars and restaurants that make it one of the city's liveliest evening districts. The Duomo of San Giovanni is a short walk away, while Porta Palazzo market lies five minutes to the north. A visit to the gate and a stroll through the lanes takes one to two hours, and more if combined with a meal. Photographers often shoot Porta Palatina from the open square in front, in late afternoon when the brick glows, and again at night when the gate is lit. Crowds are light in the daytime, with the neighbourhood becoming busy on evenings and weekends when locals gather for aperitivo. It is about ten minutes on foot from Piazza Castello, and GTT trams serve nearby Porta Palazzo. The area is safe for walking but can feel crowded and noisy late at night, so visitors seeking quiet should come earlier in the day. Information panels near the gate explain its history, and guided walks can add detail on the Roman street plan.
