It was unique to Kastamonu mansions that sensitivity of not blocking neighbor’s sun and view and the idea of the efficient use of the area. It was not easy to be a unique city. It was supposed to look into its way and watch her steps not to fall against the beauties she had seen while walking down in Kastamonu streets, which had 564 immovable cultural properties only in the city center. 400 of them were standing gorgeously over hundred years. The ground floor of the mansions was not closed or deaf as in other cities; they were the areas directly opening to life and where daily life started. While the first floors were the center of family life, the second floors were special places reserved for guests. Our ancestors reflected their subtle thoughts and considerations even on the door handle. Who knows what sadness and happiness had been lived in these places.
