[1] During the rule of governor-general Gustaaf Willem, Baron van Imhoff between 1743 and 1750, the castle of Batavia was expanded.
[1] The entrance through the new wall was formed by a gatehouse of two storeys high and topped with a dome and clock.
The construction works there were supplied partially by reusing building material from the Castle of Batavia.
Most buildings on the castle grounds had been demolished, save for a part of the Amsterdam gate and connected arcades.
[1] The gate was then reduced further to its final form, after the arcades were removed around 1870 in order to provide passage to a tramway.
