Muscat, the capital city of Oman, lies on the Arabian Sea along the Gulf of Oman. It is a port city and the seat of government and the largest city in the governorate of Muscat. The city has a rich history and a diverse cultural heritage, which is evident in its architecture, museums, and the Sultan Qaboos Grand Mosque, which is a fine example of Islamic architecture. With a backdrop of rugged mountains, the city has a mix of old and new, modern high-rises beside traditional Arab houses. The Mutrah Corniche is a promenade that extends along the waterfront and is lined with markets, parks, and restaurants, and the adjacent Mutrah Souq is a bustling traditional market. Muscat's economy is primarily driven by trade, petroleum, and porting. It has undergone rapid infrastructural development, which has transformed it into a thriving modern city, while still preserving its cultural heritage. The city's natural attractions include beautiful beaches, public parks, and the nearby Hajar Mountains, which offer outdoor enthusiasts a variety of activities such as hiking and rock climbing.
