The monument is in the form of four white curving columns holding a replica of the Crown of Johor, the crown that was commissioned by Sultan Abu Bakar in 1886, after the British proclaimed him as the Sultan of Johore through the Treaty of Friendship of 1885. The crown was last brought out in 2015 for the installation of Sultan Ibrahim Ibni Almarhum Sultan Iskandar. The monument commemorates the installation.
