NH Grand Hotel Krasnapolsky, often informally referred to as Hotel Krasnapolsky is a five-star hotel on Dam Square in central Amsterdam, Netherlands. The hotel has 468 rooms, a convention center, restaurants and a pier for boats on the Oudezijds Voorburgwal canal.The original owner of the hotel, Adolph Wilhelm Krasnapolsky, purchased the building in 1865 and turned it into a popular restaurant. He also bought the adjacent buildings and in 1879/1880 added rooms. During the same period he also built a chic conservatory with palm trees and cupola, designed by architect G.B. Salm. At that time, the use of glass and steel was a novelty and use of electric lighting was very modern for its time.To mark the exhibition of 1883 he built the business into a hotel with 125 rooms. In the late 19th century it was the only hotel in Amsterdam with hot water and telephones in each room. After World War I more buildings were purchased and the hotel was extended to Pijlsteeg.In 1971, the hotel was sold and in 1974 it became the Hotel Krasnapolsky. In the 1990s, the owners purchased a series of hotels and restaurants at home and abroad, including the Amsterdam Doelen Hotel, Schiller Hotel and Caransa Hotel. In 1998 Krasnapolsky Hotels & Restaurants N.V. (KHR) bought Golden Tulip International Golden Tulip, and in 2000 KHR was in turn bought up by NH Hoteles, the current owners of the Krasnapolsky.See alsoHotel Polen fire
