Colonial buildings and structures include those that were constructed during the colonial period. The dominant colonial styles can be divided into three periods: the Dutch Golden Age (17th to late 18th century), the transitional style period (late 18th century – 19th century), and Dutch modernism (20th century). Colonial architecture is apparent in houses and villas, churches, civic buildings and offices, mostly concentrated in the Jakarta Old Town and Central Jakarta. Architects such as J.C. Schultze and Eduard Cuypers designed some of the significant buildings. Schultze's works include Jakarta Art Building, the Indonesia Supreme Court Building and Ministry of Finance Building, while Cuypers designed Bank Indonesia Museum and Bank Mandiri Museum.
