At the heart of the city, the Marina district was designed by the Pisans in the 1200s and appears as a well-defined quadrangle that recalls the structure of the Roman castrum: at the bottom, you will find the nineteenth-century building on Via Roma and the port, at the top of Via Manno (the ancient sa Costa, today the business hub of the city) and at the east of Viale Regina Margherita. The course of the roads, regular in the flat part closest to the sea, loses linearity when it begins to rise towards the hill, becoming steep under the fortifications of Castello. As the first point of access to the city from the port, in the past it was inhabited by fishermen, sailors and merchants and has been the landing point for many people who came from distant countries, thus becoming, long ago, a melting pot of cultures and traditions, which can still be experienced today. Wandering through the narrow alleys to the many boutiques, craft shops, galleries, and make a stop at ethnic bars and restaurants. Visit the Church of San Sepolcro, Gothic-Catalan in origin, with the large Baroque chapel of the Pieta and the archaeological area of Sant'Eulalia with the Treasury Museum which holds valuable works from the churches of Sant'Eulalia, San Sepolcro and Santa Lucia.
