The bride wore an exclusive, exquisitely detailed mermaid-style gown, designed by Rosa Clara, for the ceremony.

The designer also dressed the bride’s mother and sisters and several of the wedding guests.

Guests, including Messi’s Argentine teammate Ezequiel Lavezzi, Barcelona star Gerard Pique and Shakira, were set to be given gift bags containing wine, local desert dulce de leche and other items.

The menu at the event features a ‘sushi station’, but is very much an Argentine affair, including including empanadas, traditional sweetbreads and blood sausage.

Messi and his wife met in Rosario and have been inseparable since first crossing paths as teenagers. They have two sons together.

Messi, who moved to Spain at the age of 13 and has lived in Barcelona since, arrived home to a new mural in his honour, created in anticipation of his wedding.

Guests are staying at the 188-room Pullman Hotel inside the complex, where rates start from $125 a night.

The entire area will be closed off to the public for the duration of the wedding.

Messi will have some time for a honeymoon before linking up with Barcelona for their pre-season tour of America next month.
