The Graphis Observatory at the top of the hill is close to the Hollywood landmark and is one of the best places to take a picture with it. Astronomical knowledge of eight planets and cosmic objects is on display at the observatory, which has a history of nearly 100 years. The top ball theater is built to imitate the sky. Tourists lean back on their seats, 360 176, to enjoy films about the evolution of celestial bodies. Tourists seem to be in the vast universe, naked-eye 3D technology makes everything in the universe close to hand. The open-air terrace on the top can also see the whole city of Los Angeles, with orderly streets, neat urban buildings and skyscrapers in the city. It has a special charm to see the red sun setting on the platform at sunset. Every night, the observatories with giant astronomical telescopes are open to the public free of charge. Visitors can clearly see the stars in the sky, even the surface of the moon, and enjoy the wonder of the astronomical world. Super recommend you to watch!
