The Crown Jewel in the Naghs-e Jahan Square was the Masjed-e Shah, which would replace the much older Jameh Mosque in conducting the Friday prayers. To achieve this, the Shah Mosque was constructed not only with vision of grandeur, having the largest dome in the city, but Shaykh Bahai also planned the construction of a religious school and a winter-mosque clamped at either side of it.
