BEYKOZ FORTRESS (ANADOLU KAVAGI KALESI)
It dominates the entrance to the Black Sea, which is constantly used by large tonnages. A tradition links this 14th century fortress to the Genoese, but it is Byzantine. It was disputed many times and eventually became an Ottoman at the end of the same century, under Yıldırım Beyazıt (1389-1402). With a length of 500 m and a width of 30 m to 60 m, it will be restored and equipped with a small mosque as part of a large programme undertaken by the Sultan Bayazıt II (1481-1512). During his trip to Egypt in the second half of the 16th century, the German traveller Michael Heberer Von Bretten described it in his book as being in very good condition; he took the opportunity to make an engraving. It was not abandoned until the 19th century. Note that you can also go there by several other points than Anadolu Kavağı, all along the coastal road (more deserted) or by the center of Beykoz from where the journey is a little longer and more complicated (1 hour). It is the Umurbey Yolu road that leads to it. To take it, you have to leave Beykoz along the sea: Fevzi Paşa Caddesi, then Ahmet Paşa Caddesi, junction, Yalıköy Çayırı Caddesi (left), well after school take a left (Deri ve Kundura Fabrikası Caddesi, bridge, not very beautiful), it is the Umurbey Yolu, which zigzags to the goal. A saint would rest in the mausoleum. No source proves it, but the believers do not agree with it, so they regularly visit it (huge tomb!).
