People in Israel build temporary dwellings called sukkahs in order to live there during the celebration of Sukkot.
It is customary to build temporary shelters called sukkahs in yards or on balconies. These are built in memory of the wanderings of the Jews in the Sinai Desert before the celebrations of the Sukkot feast start. It is considered a sacred duty. One should spend as much time as possible in a sukkah during the week of celebrations — eat there, rest there, and pray there. If living there is not an option, having meals in a sukkah twice a day is obligatory.
