Colchester Castle Museum opened its doors to the public for the first time 150-years-ago.
The town museum's first day of operation was on 27, September 1860 and at the beginning the collection occupied just the crypt.
The castle now contains one of the finest collections of Roman remains in the UK and was acquired by the Borough Council in 1920.
Philip Wise told BBC Essex: "The castle has had many roles over the years."
"It started off as a Royal fortress, then it was a prison, then it was a private gentleman's residence and then a museum," he said.
The Heritage manager at
Colchester Borough Council
, Philip is well acquainted with the large collections at the castle.
Viscount Cowdray donated money to the Borough Council for purchasing the castle in 1920 and shortly afterwards the collections of the
Essex Archaeologist Society
were incorporated into the museum.
The team at the castle are hoping to gain some new funding to transform the displays and make the museum into a modern exhibition.
Colchester Castle Museum
is open daily from 10am and on Sundays from 11am.
