One Hopkinton

One Hopkinton is a 990 foot tall skyscraper currently under construction in the City Circle of Newisle's Capitol Core precinct. It is currently one of the most slender buildings in the city, and is located immediately adjacent Halcyon Tower. Construction of the exterior began and completed in the morning of 23 January, 2021 and it's interior finished on 16 February. It replaced the existing 942ft tall headquarters of the now defunct Black Mesa Corp. The new building is now the 4th tallest building in Newisle and was inspired by 111 W 57th Street in New York.

Original Building
The original One Hopkinton, which was built in 2014, was a slender, 942ft tall black-concrete skyscraper, which at the time was the 4th tallest building in the city. It was connected to the neighbouring Halcyon Tower via two sky bridges to it's second and third levels. It served as the headquarters of the now defunct Black Mesa Corporation before being abandoned in 2020. During the planning of the Re-Establishment, the building was marked for demolition so the current, taller building could take it's place. Metro line U-1 ran directly underneath the building and into the first floor of Halcyon Tower before it was submerged in 2021.
