SINGAPORE - A new series of books that unveil little-known facts of the Istana will be launched on Sunday (July 28).
To be launched by President Halimah Yacob during a National Day open house at the Istana, the series of three books is titled 150 Best Kept Secrets Of The Istana.
The books will also introduce readers to some of the inner workings behind state events in the presidential estate, and were launched to commemorate the 150th anniversary of the Istana.
More details on the book, such as its availability, will be revealed on Sunday.
The Istana, completed in 1869, was built by the British colonial government to house its governors and was known as the Government House.
When Singapore attained self-government in 1959, it was handed over to the Singapore Government and renamed Istana.
Other mementos launched in the past few months to mark the 150th anniversary of the Istana include a series of souvenir medallions and Istana Cookies.
During the National Day open house on Sunday, President Halimah will also launch the second issue of the Istana Souvenir Series, which will feature four unique medallions showcasing the rich flora and fauna diversity within the Istana.
The public can also get their hands on the Istana Cookies which were launched on July 5.
