All that remains of the mosque known as Sidi Bashir Masjid is its grand entrance portal and minarets, which lend it the name Jhulta Minar (Shaking Minaret). The structure is located across from the Sarangpur gate to the east of the old walled city of Ahmedabad, near the present day train station.
Stylistically, the entrance portal relates to the Mosque of
Miyan Khan Chishti, founded in 1465 CE. The portal itself takes the form of a large arched entryway. The minarets that flank it are engaged columns with octagonal shafts toward the bottom which transform to tapering cylinders toward the top. Three balconies supported by cornices divide the shaft into sections of differing lengths. The surfaces of the shafts are intricately ornamented, featuring friezes of vegetal forms in horizontal registers.
