The Taj Mahal Palace is a historic luxury hotel in the Colaba district of Mumbai, Maharashtra state, India. The 107-year-old landmark hotel is located adjacent to the Gateway of India, overlooking the Mumbai harbor. The Taj Mahal Hotel was conceived and developed by industrialist Jamshetji Nusserwanji Tata and was inaugurated on 3 December 1903. The hotel is operated by the Taj Hotels Resorts and Palaces of the Tata Group.

The 22-floor Taj Mahal Palace has a rich blend of European and Islamic-style architecture. The hotel offers panoramic views of the Arabian Sea from the rear of the hotel, while the hotel’s entrance at the front faces west.

The hotel building has onion domes and a grand pointed arch depicting 16th-century Islamic architecture. The building has a central iconic red dome and two wings topped with smaller domes. The façade of the hotel is of oriental style.

The tower wing has arched balconies, covered by an uneven edged diadem. It offers panoramic views of the harbor. The wing incorporates unique Indian style designs such as Tanjore pillars and Udaipur-style relief panels. The hotel features luxury rooms and suites such as the impressive 465m² Tata Suite, Rajput Suite, and Presidential Suite.

The Palace or heritage wing of the hotel has 42 suites, 19 of which feature different themes such as Dolphin, Coral, Dutch, and Maratha.

The Taj Mahal Palace was originally designed by Indian architects DN Mirza and Sitaram Khanderao Vaidya. The project was completed by the British architect and engineer WA Chambers. The sea-facing hotel structure is built on a 40ft-deep foundation. Khansaheb Sorabji Ruttonji Contractor was the builder.

During World War I, the hotel was used as a hospital and kitted out with 600 beds.

The Taj Mahal Palace was expanded in the 1970s with the adjacent tower block. This extension increased the number of rooms from 225 to 565 and saw the addition of food and beverage outlets and public areas.

The tower building was designed by US architect Melton Bekker, while Swiss designer Dale Keller was responsible for the interiors.

The tower wing underwent refurbishment in the late 1990s: the top floors were modernized and updated with the latest communication facilities and modern furniture.
