It has taken 227 years, but Portugal's stunning crown jewels have finally gone on display in a giant strong room inside the country's long unfinished royal palace.

The Ajuda Palace overlooking the capital's historic Belem district was home to Portugal's last royal dynasty, the Braganzas, whose reign ended when the country became a republic in 1910.
