While walking among the streets in Kastamonu, a mosque with stone walls attracted his attention. When he entered the mosque, which appeared to be modest from the outside, he was glorified. Atabey Gazi Mosque, popularly known as the 40-masted mosque, was located on the skirts of Kastamonu Castle. As one of the oldest buildings in the city, the mosque was built by Seljuk Hüsameddin Çoban Bey in 1271, with its ceiling and pillars made of wood, and the walls were made of rubble stone cutting. According to the rumors, when the city was conquered, this temple was converted into a mosque, as a symbol of the conquest, and Atabey Gazi gave a sermon with a sword in it. This is why the mosque also called Fateh (The Conquest) Mosque. When he learned that the sermons of the Friday prayers have been given a symbolic sword as a tradition since that day, he was convinced that he might encounter a surprise about the past any moment after what he lived in this city.
