The two World Trade Centre towers used to be the most recognized landmarks of the city. Before they were completed in 1997, the adjacent Bank of Ceylon tower was the tallest structure and the most prominent city landmark. Before the skyscrapers were built it was the Old Parliament Building that stood majestically in the Fort district with the Old Colombo Lighthouse close to it. Another important landmark is the Independence Hall at Independence Square in Cinnamon Gardens. Even before the parliament was built some claim that the Jami Ul-Alfar Mosque was recognized as the landmark of Colombo by sailors approaching the port. The mosque is still one of the most visited tourist sites in Colombo. Another landmark is St.Paul's Church Milagiriya, one of the oldest churches in Sri Lanka, first built by the Portuguese and re-built by the British in 1848. The Fort district has the famous Cargills & Millers complex that is protected by a special government law from demolition. This is done mainly to preserve the historic beauty of the Fort area. The Galle Face Green is the city's largest and most elegant promenade. Lined with palm trees and adjacent to the coast, this mile-long stretch in the heart of the city is a constant beehive of activity. The green is especially busy on Fridays and Saturdays. In the evenings it plays host to families and children playing sports and flying kites, lovers embracing under umbrellas and health enthusiasts taking their evening walks. There are numerous small food stalls and a small stretch of beach. The green was recently[when?] given a makeover and since then has been even more popular with the local community. The Green frequently hosts international and local concerts and performances, such as the recently concluded World Drum Festival. Cannons that were once mounted on the rampart of the old fort of Colombo laid out for observance and prestige at the Green, giving a colonial touch to the city. The famous colonial styled Galle Face Hotel, known as Asia's Emerald on the Green since 1864, is adjacent to Galle Face Green. The hotel has played host to distinguished guests including the British Royal Family and other royal guests and celebrities. After a stayed at the hotel, Princess Alexandra of Denmark commented that "the peacefulness and generosity encountered at the Galle Face Hotel cannot be matched." Also facing Galle Face Green is the Ceylon Inter-Continental Hotel, Sri Lanka's first five-star hotel. Around the corner from Galle Face are prominent coffee bars, chic bars and boutiques.
