Changes After Construction
It was built as a small mosque by Balaban Ahmed Baba, who belonged to the İsfendiyaroğulları dynasty that ruled in the Kastamonu region.
In 1764, it also began to be used as a tekke by Sheikh Yağcızade Seyyid Ahmed Efendi, one of the imams of the mosque.
The structure was badly damaged in a fire in 1829 and was completely demolished.
According to the inscription above its gate, it was rebuilt in 1889 by Sheikh Âşir Efendi and his wife Ayşe Sıdıka.
The three-storey wooden structure, which continued to function as a mosque until 1948, later fell into ruin due to neglect and was demolished.
By the 2000s, only the garden wall, cemetery, and Baroque-style fountain of the historic structure had survived. It was rebuilt in 2009 by Üsküdar Municipality.
Today, it is used as the Üsküdar Municipality Balaban Tekke Cultural Center.
