Heraklion was surrounded by high walls and bastions and extended westward and southward by the 17th century. The most opulent area of the city was the northeastern quadrant where all the elite were gathered together. The city had received another name under the rule of the Ottomans, "the deserted city". The urban policy that the Ottoman applied to Candia was a two-pronged approach. The first was the religious endowments. It made the Ottoman elite contribute to building and rehabilitating the ruined city. The other method was to boost the population and the urban revenue by selling off urban properties. According to Molly Greene (2001) there were numerous records of real-estate transactions during the Ottoman rule. In the deserted city, minorities received equal rights in purchasing property. Christians and Jews were also able to buy and sell in the real-estate market.
