Queen Elizabeth II gave summer vibes in a pale green coat and matching hat as she and her husband Prince Philip visited the Giant’s Causeway in Northern Ireland where the hit drama “Game of Thrones” is filmed on Tuesday. The British royal couple are on a two-day visit to Northern Ireland to celebrate her 90th birthday. The nonagenarian queen and her 95-year-old husband braved blustery conditions to view the landmark UNESCO World Heritage site in Co Antrim.

Even in the gloomy day, Elizabeth added color to the atmosphere in a pale green coat. She opted for a white floral dress underneath and wore a pale green hat with green and white floral accents. Elizabeth, who loves pearls, accessorized with a three-string pearl necklace, matching earrings and a silver brooch.

The queen wore white gloves and a slick of deep pink lipstick. Her famous black leather Launer handbag was not seen in her hand on the occasion. She wore her trusted pair of black loafers.

The Duke of Edinburgh, meanwhile, wore a sharp black suit paired with a crisp white shirt. He paired his outfit with a blue tie and black lace-up shoes. The Giant’s Causeway and the surrounding countryside have witnessed a major surge in popularity in recent years due to the filming of “Game of Thrones.” The UNESCO world heritage site comprises 40,000 interlocking basalt columns, the majority hexagonal, that were created in a volcanic eruption.

Ballinroy, which is located about 15 minutes from the Causeway is the town of Pyke in the series. Besides, fans of the hit series can enjoy Game of Thrones-themed tours from Belfast. Neville McConachie, the visitor experience supervisor at the National Trust site, explained theories on the causeway’s creation to the queen and Philip. “She was asking about the formation of the rock and I was telling her it was either caused by nature or a giant, and I believe a giant,” he said. The queen was cheered on by tourists visiting the landmark.

The royal couple also visited the nearby village of Bushmills to unveil a statue to VC recipient Robert Quigg. The soldier was awarded the highest military honor for bravery during the Battle of the Somme in 1916. There was a huge crowd to welcome the royal couple in spite of the inclement weather.
