The Duke of Bragança was the guest of honour at the cerimony of the 872 years of Sintra's Foral (Charter).

The Suke, a Sintra resident, discussed with mayor Marco de Almeida some issues regarding the development of Sintra.

Sintra was conquered by King Afonso Henriques in 1147, the same year as Lisbon, and was always a favourite spot for the portuguese kings.

The Moorish castle is one of the main attractions in Sintra
