The Duke of York has visited the spot where the Titanic was built during a tour in Belfast.
Prince Andrew viewed the cavernous dry dock in which the liner, which sank with the loss of more than 1,000 people, was prepared for sea.
Last year marked the centenary of one of the deadliest peacetime maritime disasters after the vessel hit an iceberg in the North Atlantic. The Duke also went to the pumphouse which operated the dock.
He visited the nearby Northern Ireland Science Park and innovation centre for a short overview. The park was established in 1999 as an internationally-recognised knowledge-based centre to encourage new businesses.
The Prince visited two companies within the innovation centre - Path XL, a global pioneer in the use of the web for digital pathology, and Sophia Research, which specialises in analysing text.
He will later attend a dinner marking the role of philanthropy in driving the economy.
