The Real Madrid star tied the knot with Emma Rhys-Jones in one of the villas at a 17th century fortress in Majorca called La Fortaleza, according to local reports.
Diario de Mallorca said the secret wedding took place on June 20 as part of a three-day celebration which lasted until June 23.
It also said the couple flew in a band from Britain to entertain guests and interior designers from as far away as Germany – and made the firms and workers hired for their big day sign confidentiality agreements which included fines of up to £44,800 for leaking any photos.
The couple’s three children, Alba Violet, six, Nava Valentina, three, and Axel Charles, one in May, were present at the ceremony along with Bale’s parents Frank and Debbie.
Emma’s grandparents John and Eva McMurray complained at the weekend they had been excluded along with her fraudster dad Martin, 55.
The couple were due to marry at Vincigliata Castle, Tuscany, last year and earlier this year Bale was reported to have booked the private island of Tagomago off Ibiza where he got engaged in 2016 for the new ceremony.
But the 29-year-old Wales winger and his 27-year-old partner reportedly ended up exchanging vows instead at La Fortaleza in Majorca, a British-owned estate where 2016 BBC spy thriller The Night Manager starring Hugh Laurie was filmed.
Netflix series Turn Up Charlie starring Idris Elba was also filmed at the stunning venue, owned by Conservative party donor Lord Lupton.
A week-long stay at the property – offered as an auction prize at a Tory Black and White Ball fundraiser – went for £220,000 four years ago.
Before travelling to Majorca, Bale is believed to have celebrated his stag do during a Costa del Sol golfing holiday with several Brit pals.
He was spotted at an exclusive golf club in Marbella and another in nearby Sotogrande close to Gibraltar in the run-up to his wedding.
The Sun on Sunday revealed last July how Bale and his then-fiancee had called off their wedding at an Italian castle so Emma could heal a rift with her former jailbird father Martin.
He was among the relatives “uninvited” to the wedding after a case with cash, cocaine and watches went missing from her elderly grandparents’ home.
Emma fell out with her dad after he moved in with a florist half his age within weeks of being freed from jail in the US.
He was sentenced to six years in prison after admitting ripping off more than 250 investors as part of a boiler room fraud.
The 55-year-old only met his two oldest grandchildren for the first time in an emotional reunion with Emma after he flew home in August 2017.
Their meeting at a secret address in Cardiff was described at the time as the first in six years.
Bale celebrated his 27th birthday on Tagomago, the private island off Ibiza where he was initially thought to have rescheduled this year’s wedding.
Cristiano Ronaldo stayed on Tagomago in 2014. Ronnie Wood also holidayed there the same year.
La Fortaleza, which overlooks the bay of Pollensa in north-east Majorca, was purchased by Lord Lupton in 2011 for £30million although the original asking price is believed to have been around the £75m mark.
It was described ahead of the sale as Spain’s most expensive property.
The original fort was built in 1628 to defend Majorca against invaders. By the time Lord Lupton’s family bought it the estate had been expanded to include a helipad, two swimming pools and seven villas with 17 en-suite bedrooms.
In The Night Manager it was the lair of “the worst man in the world” – billionaire arms dealer Richard Roper who was played by Hugh Laurie.
Spanish model Helen Lindes and basketball player Rudy Fernandez married there in July 2015. Guests included NBA star Pau Gasol.
None of Bale’s Real Madrid teammates are understood to have attended the wedding.
The former Spurs star, booed by some fans as he turned up for his first day of training on Monday, is said to be out of favour at the Spanish giants and rumoured to be facing a return to the Premier League.
