A decorated river boat on the Nile River photographed at night from the Zamalek (El-Zamalek) corniche walkway in Cairo. The boat's colorful lights reflect on the dark water while illuminated high-rise buildings line the opposite bank, capturing the urban nightscape of central Cairo. Zamalek is an upscale island district in the middle of the Nile, known for its promenade and views of Cairo's skyline.
