Input: Article: At the centre of this wing is the famous balcony with the Centre Room behind its glass doors. This is a Chinese-style saloon enhanced by Queen Mary, who, working with the designer Sir Charles Allom, created a more "binding" Chinese theme in the late 1920s, although the lacquer doors were brought from Brighton in 1873. Running the length of the piano nobile of the east wing is the great gallery, modestly known as the Principal Corridor, which runs the length of the eastern side of the quadrangle. It has mirrored doors, and mirrored cross walls reflecting porcelain pagodas and other oriental furniture from Brighton. The Chinese Luncheon Room and Yellow Drawing Room are situated at each end of this gallery, with the Centre Room obviously placed in the centre.

Now answer this question: The lacquer doors in the Centre Room were brought from Brighton in which year?

Output: 1873

Input: Article: Louis did not leave a son as heir after his death in 1382. Instead, he named as his heir the young prince Sigismund of Luxemburg, who was 11 years old. The Hungarian nobility did not accept his claim, and the result was an internal war. Sigismund eventually achieved total control of Hungary and established his court in Buda and Visegrád. Both palaces were rebuilt and improved, and were considered the richest of the time in Europe. Inheriting the throne of Bohemia and the Holy Roman Empire, Sigismund continued conducting his politics from Hungary, but he was kept busy fighting the Hussites and the Ottoman Empire, which was becoming a menace to Europe in the beginning of the 15th century.

Now answer this question: Upon taking the throne of Hungary where did Sigismund establish his court?

Output: Buda and Visegrád
