Hats were the order of the day as racegoers arrived at Ascot

The famous summer sporting and social event returned to Berkshire on Tuesday after being held at York last year.

During the 20-month redevelopment the track and a golf course were moved and the old stands demolished and replaced.

Traditional top hats and bright milliners' creations were on display as visitors passed through the iron gates.

The Queen is set to open the redeveloped course later and take part in the traditional Royal carriage procession.

The Prince of Wales and the Duchess of Cornwall are also set to attend the opening.

One of the first racegoers to go inside, Tracey Hopkins, 38, from Port Talbot, south Wales, thought the new grandstand looked superb.

She said: "It looks absolutely amazing. We've been coming here for about 20 years and it really looks good.

Ascot has been closed since 2004 for redevelopment work

But Colin Sheppard, a 70-year-old seasoned visitor from Chichester, West Sussex, was unimpressed.

"I'm old-fashioned so I can't stand the architecture. I'm hoping it's functional. It looks like Munich Airport, which I detest, but it's a matter of taste," he said.

"What matters, though, is can I see the racing."

Temporary traffic regulations have been implemented during five-day meet, including a one-way system around the racecourse.

Thames Valley Police are urging racegoers to allow plenty of time for their journeys during the five days.
