Landmarks in Los Angeles and a further three American Olympic host cities are set to be lit up to honour the International Olympic Committee’s (IOC) final host city announcement tomorrow in Lima.

Los Angeles are poised to be awarded the 2028 Olympic and Paralympic Games at the IOC Session here, with Paris set to become hosts for 2024.

Griffith Observatory, the Hollywood Bowl, and the US Bank Tower in the city are due to be lit up this evening and tomorrow to mark the decision.

Los Angeles 2028 revealed the landmarks will be illuminated in the colour of the city’s sunsets, which they believe will show their commitment to use their creative and entertainment community to inspire young people to engage with sport.

“The nearly 50 landmarks and buildings glowing in Los Angeles 2028 colours show how excited our city and our country are to bring the Games back and underscore the spectacular setting that Los Angeles offers for the Olympic and Paralympic Games in 2028,” said said Los Angeles 2028 chiefe executive Gene Sykes.

"This show of support demonstrates our city’s wealth of entertainment venues, cultural attractions and natural treasures that, enhanced by the power of Hollywood storytelling, will help Los Angeles 2028 engage a brand new generation of Olympic and Paralympic enthusiasts."

Los Angeles City Hall, Los Angeles International Airport, the Rose Bowl and the StubHub Center are among the other venues which will be illuminated in the city.

The Los Angeles Memorial Coliseum, the UCLA and the recently opened Wilshire Grand, which was first illuminated to welcome the IOC Evaluation Commission Committee, will also be lit up.

It has also been confirmed that St. Louis, host of the 1906 Summer Olympics, will light up the exterior of St. Louis Union Station to mark the occasion.

Squaw Valley and Lake Placid, which staged the 1960 and 1980 Winter Olympics respectively, will also illuminate venues.

Lake Placid will light its 1980 Olympic ice hockey venue, while Squaw Valley will illuminate its iconic Olympic sign.

There, however, appear to be no plans to mark the occasion in Atlanta or Salt Lake City which, as hosts of the 1996 Summer and 2002 Winter Olympics, were the last two American cities to host the Games.
