The island of Kos is characterised by the traditional architectural style of the Dodecanese islands, yet the local elements were altered by the island's touristic growth. The huge hotel units, built in the resorts and the major cities, changed the post-quake view of the island with the two-storeyed buildings and the wooden blue doors and windows. Havouzia, the historic part of the city of Kos situated behind Agia Paraskevi, is the only area declared preserved traditional settlement, reminding of the old life-style. The houses are built of stone and lime, while the doors and the windows are framed with thin stone and the roofs are flat, in order to collect the rainwater. The rapid growth of the island left few opportunities to preserve the traditional popular customs. In spite of this fact, some of the elderly locals try to communicate to the younger ones, the value and the importance of old customs such as "Klydon", the cup with the water taken from forty waves, inside which the young girls put their jewelry the night before the celebration of Agios Ioannis and took them back the following day, under the sounds of "mandinades" praising their love and beauty. A great effort is being made for the preservation of the ceramics tradition of Kos. The Archaeological Service declared as preserved only one ceramics workshop, situated in Kardamena, where the people still manufacture pots called "tsoukalaria". The island maintains the tradition regarding the lyricists, the instrument players and the dancers and not one opportunity for celebration is wasted and the tables are set and the feast begins under the presence of large of small crowds, depending on the town or village.
