Gereja SionĀ (Indonesian forĀ "Zion Church") is a historic church located in Pinangsia Administrative District,Ā Taman Sari,Ā Jakarta,Ā Indonesia. Dating from 1695, it is the oldest church still standing in Jakarta. The church was formerly known asĀ De Nieuwe Portugeesche BuitenkerkĀ ("The New Portuguese Outer Church"), referring to its position on the outside of the city wall, as opposed to Portugeesche Binnenkerk, "the Portuguese Inner Church"). The church was also known asĀ BelkitaĀ during the period. The church was built outside the old city walls for the so-called "black Portuguese" - the Eurasians and natives captured from Portuguese trading posts in India and Malaya and brought to Jakarta (then Batavia) as slaves. Most of these people were Catholics, but were given their freedom on the condition that they joined theĀ Dutch Reformed Church, and the converts were known asĀ MardijkerĀ or the liberated ones.
