It is the location of the Mount Wilson Observatory, which is an important astronomical facility in Southern California with historic 60-inch (1,524 mm) and 100-inch (2,540 mm) aperture telescopes, and 60-foot (18.3 m) and 150-foot (45.7 m) tall solar towers.
An engraving of Huygens's 210-foot aerial telescope showing the eyepiece and objective mounts and connecting string. An aerial telescope is a type of very long focal length refracting telescope, built in the second half of the 17th century, that did not use a tube. [1]
The roller coaster features seven inversions, a 150-foot (46 m)-tall lift hill with a 150-foot (46 m) drop, and the first Sea serpent roll element ever built on a B&M roller coaster. The ride is the longest coaster in Northern California at 3,937 feet (1,200 m) long and is notable as having one of the largest vertical loops in the world at 128 ...
The 150-foot (46 m) focal length solar tower expanded on the solar tower design with its tower-in-a-tower design. (The tower is actually 176 feet (54 m) tall.) An inner tower supports the optics above, while an outer tower, which completely surrounds the inner tower, supports the dome and floors around the optics.
The building is enclosed in a lattice consisting of white aluminum fins and perforated sunshades, which reach out as much as two feet beyond the glass skin. [16] The tower's silhouette is smoothly tapering off toward the top. [16] Salesforce Tower is 61 stories tall, [3] and covers 1,400,000 sq ft (130,000 m 2) of floorspace. [19]
The train leaves the station and starts climbing the 150-foot (46 m) vertical lift hill. Upon reaching the top, the train is held for five seconds before plunging at a 96-degree angle. The train reaches a max speed of 57 miles per hour (92 km/h) and heads through a negative-g stall loop, a one-of-a-kind inversion.

Past that was a grand hall along 43rd Street, which was modeled on the Versailles chapel and measured 150 feet (46 m) long by up to 50 feet (15 m) wide. [ 8 ] [ 30 ] [ 52 ] The hall's design features were also inspired by that of the Paris Opera House 's foyer, with white marble columns, balustrades, and a grand staircase flanking the hallway.
