This mosque was named "Kurşunlu” Mosque" because its central dome was covered with lead. Kurşunlu Mosque and Fountain is the only work of Mimar Sinan, who made 12 works in the city, which has survived to the present day in Kayseri. It attracts attention with its interior decorations, pulpit and domed fountain with pointed arches on eight columns in the courtyard. Kurşunlu Mosque, which is a classical Ottoman period architectural work, is one of the most beautiful mosques in Kayseri in terms of embroidery and ornaments.
The last congregation place of the mosque, which was built of smooth cut stone, has a double portico, as in Mimar Sinan's Mihrimah, Atik Valide and Eminönü Rüstem Paşa mosques in Üsküdar, Istanbul.
