One of the most iconic buildings in Europe has gone gay to celebrate marriage equality in France.

While some have argued the Bastille Day celebrations that lit up the Eiffel Tower in gay pride colors was a tribute to South Africa’s Rainbow Nation, many say it was clearly about the end of the fight for same-sex marriage.

This year, the theme of the Paris fireworks was France’s motto: ‘Liberty, Equality, Fraternity’.

The show was attended by hundreds of thousands of people on the Seine and the Champ de Mars who watched the night sky with several million tuning in to watch iat home.

On Twitter, one user said: ‘Very nice tribute to the passage of #MarriageForAll with having a rainbow Eiffel Tower. #14July’

‘So happy to see the Eiffel Tower adorned with a rainbow flag!’ another said.

Christine Boutin, leader of the French Christian democratic party, was less than happy to see the rainbow flag light up the iron lady.

She retweeted a message saying: ‘The fireworks and the Eiffel Tower are the colors of LGBT people! On 14 July we will stop at nothing to stop this law!’

It led to several people making jokes at her expense, such as ‘Gay flag on the Eiffel Tower? Boutin just died of a heart attack.’

In the past year, same-sex marriage has divided France. In an attempt to stop the Socialist government led by President François Hollande, the anti-gay right-wing increased the pressure.

Several protests for and against same-sex marriage attracted hundreds of thousands of people, and there was a sharp increase in homophobia.

It led to the death threats made against French officials, beatings happened, and one gay rights activist Clémént Méric was left brain dead after an attack.

But the first gay couple was married in Montpelier at the end of May, with several others following in their footsteps.

Despite a few half-hearted protests at the tennis French Open, Tour De France and a rather homoerotic shirtless rally on a beach, same-sex marriage continues to be law.
