Translation from the previous post:
"On 22 October one of the coffins was moved out of the Royal Vaults, to store the remains in a new coffin. It concerns the remains of Queen Anna Paulovna. The new coffin will be placed at the original location of the old coffin in the Royal Vaults in the Nieuwe Kerk in Delft.
The re-encasing will take a few days and will take place in Rotterdam. The activities are carried out by the 'Special Funerals' team of Monuta. The members of the royal family adhere to the fact that the remains of their ancestors are kept in a dignified and sustainable way in the Royal Vaults."
Anna Paulovna Romanova, Grand-Princess of Russia (1795-1865) was a daughter of Tsar Paul I of Russia and his wife Sophia Dorothea Augusta Louisa of Württemberg, better known in Russia as Tsarina Maria Feodorovna. When Anna was six years old, the Tsar was murdered and succeeded by her eldest brother, Alexander. In 1816 the Grand-Princess married the Prince of Orange (the later King Willem II of the Netherlands, Grand-Duke of Luxembourg).
