Abigails: A cacher has kindly told me that the building the cache is outside is getting boarded up for refurbishment and will make the cache inaccessible. Therefore, I think its time for this cache to go. It has had 295 finds and 35 favourite points which I am really pleased about.
The buildings are (from left to right):
Sydney Opera House
HSBC Building in Hong Kong
Millennium Bridge, London
Swiss Re Building. AKA The Gherkin
Allianz Arena in Munich
Birds Nest Stadium in Beijing
The person that connected them was Sir Ove Nyquist Arup and all the above buildings were engineered by his eponymous firm. The cache co-ordinates were placed at Kings Cross Station which was also designed by Arup.
The final was placed outside 13 Fitzroy Street which was the headquarters of Arup for many a year. Their head office is now opposite at 8 Fitzroy Street. I worked at Arup for over 10 years, but now have moved on and therefore I’m freeing up space for someone else.
