London’s Shard tower will be inaugurated on Thursday to great fanfare — but Europe’s tallest skyscraper has won as many critics as it has admirers.

The inauguration of the jagged-tipped tower, which at 310 metres (1,017 feet) dwarfs nearby landmarks such as St Paul’s Cathedral and the Houses of Parliament, has been carefully timed.

Branded “an icon for London” by its developers, the Shard will be completed just ahead of the Olympic Games, which open on July 27.

With its striking silhouette, 95 floors and a viewing deck offering 360-degree panoramas, developer Sellar Property hopes the Shard can become a major tourist attraction.

“It will become as essential a part of a visit to London as going to the top of the Empire State Building is for visitors to New York,” said Irvine Sellar, the company’s chairman.

The inauguration will be as bold as the skyscraper’s shape, with a spectacular night-time laser show lighting up the city’s major landmarks to live music from the London Philharmonic Orchestra.

Designed by Renzo Piano, the Italian architect behind the colourful Pompidou Centre in Paris, the glass tower sits south of the River Thames at the heart of a wider regeneration project in the London Bridge district.

The idea was to build a “vertical city” with capacity for 12,000 people, featuring a five-star hotel, luxury restaurants, 600,000 square metres of office space, and shops.

There will also be ten flats with stunning views on floors 53 to 65 — the highest residential properties in Britain.

But any would-be resident will need a hefty bank account as well as a strong head for heights, because the apartments will reportedly cost up to $78 million each.

“The Shard is the perfect metaphor for modern London,” one commentator observed recently in the Guardian newspaper.

“Expensive, off-limits and owned by foreign investors — the Shard extends the ways in which London is becoming more unequal.”

The $705 million project teetered on the brink of cancellation in 2007, when developers struggled to find investors as the credit crunch set in.

Qatar came to the rescue — funding 95 percent of the construction, and adding the Shard to a bulging portfolio of London properties that includes the Olympic Village and the famous Harrods department store.

Qatar’s Prime Minister Hamad bin Jassim al-Thani will attend the inauguration on Thursday, alongside Queen Elizabeth II’s second son, Prince Andrew.
