 Due to financial problems however, much of the old town, its wall, and Kasteel Batavia were torn down for construction materials to build new government and civic buildings, such as the Palace of Daendels (now department of Finance) and the Harmonie Society Building (demolished).The only remnant of the area of Kasteel Batavia is Amsterdam Gate, which was completely demolished in 1950.The city continued to expand further south as epidemics in 1835 and 1870 forced more and more people to move out of the old city to the newer spacious, green and healthier Weltevreden neighborhood.
