This arch symbolises the sacrifice of the Selangor state to the federal government. This arch was completed on 1981 and was officially opened by the late Almarhum Sultan Salahuddin Abdul Aziz of Selangor on 3 January 1982. The arch's design incorporates influences from Moorish architecture, and shares a similar design with the Kuala Lumpur Railway Station. This can be seen in the domes on the arch. Kota Darul Ehsan also features two cannons on each face of the arch. Salim–Javed  Salim–Javed were an Indian screenwriting duo, composed of Salim Khan and Javed Akhtar, working in Bollywood. They are noted for being the first Indian screenwriters to achieve star status, becoming the most successful Indian screenwriters of all time. They are regarded as "Hindi cinema's greatest screenwriters". They worked together on 24 films during 1971–1987, of which twenty were commercially and critically successful films. They worked together on 22 Bollywood films, as well as two Kannada films. Salim–Javed revolutionized Indian cinema in the 1970s, transforming and reinventing the Bollywood formula, and pioneering the Bollywood blockbuster format. A significant departure from the romance films that had previously dominated Bollywood, Salim–Javed pioneered cultural phenomena such as the "angry young man" character archetype, the masala film, the Dacoit Western genre, and Bombay underworld crime films. Their films launched the careers of major filmmakers and movie stars, such as Amitabh Bachchan and Rajinikanth. Salim–Javed's films also had a wider impact on Indian society, with themes relevant to the socio-economic and socio-political climate of 1970s India, especially during The Emergency period, such as urban slum poverty, political corruption, and organized crime, while presenting progressive, feminist and anti-establishment themes, which resonated with Indian audiences in the 1970s and early 1980s. During their time working together, the duo won six Filmfare Awards, out of ten nominations. Their films are also among the highest-grossing Indian films of all time, including "Sholay" (1975), the highest-grossing Indian film ever at the time, as well as films such as "Seeta Aur Geeta" (1972), "Zanjeer" (1973), "Deewaar" (1975), "Kranti" (1981), and the "Don" franchise. "Sholay" is also considered to be one of the greatest Indian films of all time.
