Jepara Baitul Makmur Grand Mosque, Islamic prayer complex in Jepara, Indonesia.

Jepara Baitul Makmur Grand Mosque is an Islamic prayer complex featuring multiple minarets, a central dome, and white walls decorated with geometric patterns throughout. Inside, there are separate prayer spaces for men and women, along with ablution facilities and parking areas for visitors.

The mosque was built during the reign of Pangeran Arya Jepara, adopted son of Ratu Kalinyamat and leader of the Kalinyamat Kingdom, entirely from teak wood. It was renovated in 1686, when the roof was reduced from five tiers to three, again in 1929, and in 1989, when a modern concrete structure replaced most of the timber to accommodate growing congregations.

The carved teak of the mihrab carries calligraphy of Surah Al-Ikhlas, Al-Falaq, An-Nas, Al-Kafirun and Ayat Kursi, and the four supporting pillars are carved at their bases. The motifs combine Majapahit convex and concave geometry, Javanese Semarangan leaf scrolls and Pajajaran convex carving patterns.

The mosque stands on the south side of Alun-Alun Jepara in Kauman, a few metres from the Pendopo Kabupaten Jepara. Visitors enter the prayer hall without shoes and in modest clothing; the carved teak porch, upper windows and main door are the parts to look at before going in.

The name Baitul Makmur means House of Abundance and reflects how this place serves as a center for spiritual growth and community well-being. The name was chosen to express hope that all who come here find blessings and prosperity.
