Guide and Client walk Kota Tua Jakarta, also known as the Old Batavia (Oud Batavia), is a small area in Jakarta, Indonesia. This special area has an area of 1.3 square kilometres across North Jakarta and West Jakarta (Pinangsia, Taman Sari and Roa Malaka). Nicknamed the "Asian Gem" and "Queen of the East" in the 16th century by European sailors, Jakarta Lama was considered the trade centre for the Asian continent because of its strategic location and abundant resources.

Sunda Kelapa, better known as Pasar Ikan (meaning fish market) is located at the mouth of the Ciliwung River. The fish catch of the day was auctioned in the early morning at the old fish market. The street leading to it was lined with shops selling all sorts of shells, dehydrated turtles, lobsters and mostly everything the seafarer might need. This 500-year-old harbour area was a vital link to markets of the outside world for the 15th century kingdom of Pajajaran. It was formerly the harbour town of Sunda Kelapa where the Portuguese traded with the Hindu Kingdom of Pajajaran in the early 16th century. Since than this port has belonged to the portuguese and Dutch. Dutch domination of Jakarta and the rest of Indonesia began from this area, whereas the remnants of Kasteel Batavia, an old fort and trading post of the Dutch East Indies Company can still be seen now. Sunda Kelapa is at present a fisherman's wharf and an inter island port. Tall-misted Bugis schooners from South Sulawesi anchoring there offer a picturesque scene. They belong to one of the last-fleets of sailboats in the world and still ply the seas between the islands, as they did centuries ago, carrying merchandise. Tough little remains of bustling old Sunda Kelapa except the name, the harbour is still one of the most important calls for sailing vessels from all over Indonesia. The magnificent and brightly painted Makassar schooner called Pinisi is still an important means of transporting goods to and from the outer islands. This is one of the finest sights in Jakarta. Wander around the old Sunda Kelapa port, watching gangs of sinew-stretched coolies smoking pungent clove-laced cigarettes unload cargos of timber, coal and spices from stunning wooden schooners. Hire a dugout canoe and paddlers and enjoy the waterside scenery. The boats also go to the nearby old fish market, which can be reached easily by foot from the port and is free to enter. Work starts here at 3am and it's essential to arrive by 6am to see the best of the action.

Istiqlal Mosque in Jakarta, Indonesia is the biggest mosque in Southeast Asia, befitting its location in the largest Muslim country in the world (in terms of population). The mosque was constructed to conform to then-President Sukarno's grand vision of a strong, multi-faith state with the government at its centre: Istiqlal Mosque stands across the street from the Catholic Jakarta Cathedral, and both places of worship stand next to Merdeka Square, home to Monas (Independence Monument) which towers over them.

After the arrival of Dutch East India Company in 1619, the Roman Catholic Church was banned in the East Indies and only survived in Flores and Timor. The Netherlands was known to support Protestantism and tried to limit the influence and authority of the Holy See. During the Napoleonic Wars, the Netherlands fell under the French Empire, including its possession, the colony of Dutch East Indies. In 1806 Napoleon Bonaparte installed his Catholic younger brother Louis Napoleon (Dutch: Lodewijk) as the King of The Netherlands. Since then, the Catholic Church has been free to operate in the East Indies. The Commissary General of Batavia, Du Bus de Gisignies (1825–1830), was credited with providing land to build the first Catholic church in Batavia. The former residence of General de Kock in the Weltevredeen area was renovated to be a church. Monseigneur Prinsen blessed and inaugurated the church on 6 November 1829 and named it "Our Lady of the Assumption." The church was renovated in 1859, but collapsed on 9 April 1890. The present church is the one rebuilt between 1891 and 1901. Pastor Antonius Dijkmans, SJ was appointed as the architect. Construction was halted due to a lack of funding, but the church's new bishop, Mgr E. S. Luypen, SJ, raised the necessary funds in The Netherlands and architect MJ Hulswit resumed construction in 1899. "De Kerk van Onze Lieve Vrowe ten Hemelopneming - The Church of Our Lady of the Assumption" was blessed and inaugurated by Mgr Edmundus Sybrandus Luypen, SJ on 21 April 1901. The church was renovated in 1988 and 2002.
