It is always a joy for royal fans to see royal couples with their adorable brood. From Zara and Mike Tindall to Queen Mary and King Frederik of Denmark, royal engagements are often a family affair.
With royal couples like the Prince and Princess of Wales having three children born a couple of years apart, and the same for royal parents like King Felipe and Queen Letizia of Spain, it can often be forgotten that there are some rarely-seen royal twins in several dynasties throughout Europe and beyond.
Meet the royal siblings you may not have realised are in the regal twin roster…

Princess Charlene and Prince Albert welcomed their son and daughter in 2014 at the Princess Grace hospital. Prince Jacques is the heir to the Monogasque throne, despite being born two minutes after his sister, as male-favoured primogeniture rules still stand in Monaco.
