Placa or Stradun is the limestone-paved main street in the Old Town of Dubrovnik and the favourite promenade and gathering place of locals and tourists. It divides the Old City into the northern and southern parts and is the shortest way between the western Pile and the eastern Ploce City gates. On each of its ends there is a fountain (Small and Great Onofrio fountains) where you can refresh yourself in the hot summer days. Until the end of 11th century Stradun used to be a marshy channel that separated the settlement on the islet Laus from the settlement Dubrava on the mainland. Gradually the channel was filled up and it became the most important street in the City. Stradun and the alleys on both of its sides are filled with cafés and restaurants, as well as numerous souvenir shops. While coffee can be quite pricey on Stradun, there are many reasonably priced cafés in the nearby alleys.
