Sultan Ibrahim Building, British colonial building in Johor Bahru, Malaysia

The Sultan Ibrahim Building is a former state secretariat on Bukit Timbalan in Johor Bahru, designed by Palmer and Turner in a Saracenic style with a landmark tower. Its reinforced concrete frame is faced with stone and rests on 3,000 tons of structural steelwork fabricated in Singapore by United Engineers Ltd. It was completed in 1940 and opened by Sultan Ibrahim.

The structure was completed in 1940 and remained the tallest building in the city until new tower blocks appeared in the 1970s. During World War II, it served as a military center, which underscores its importance in regional history.

The building's Saracenic design, with its tower, was drawn up by the British firm Palmer and Turner, which also designed the Johor Bahru General Hospital and landmarks in Singapore. The Johor State Legislative Assembly met here before moving to Kota Iskandar, and the building later hosted the opening of new assembly sessions. Sultan Ibrahim, who opened it, had been awarded Japan's Order of the Rising Sun in 1934.

The property is protected and access is restricted, so visitors should check with security beforehand about entry possibilities. It is useful to note the hilltop location, as this affects both the view of surroundings and how you approach the site.

In 1942 General Yamashita Tomoyuki based himself at the building and at Istana Bukit Serene to plan the invasion of Singapore, using the hilltop site as a command centre to watch British activity across the strait. Parts damaged during the invasion were never rebuilt, and the scars remain visible on the facade.
