Dublin buildings of all types and periods will be open to the public for free this weekend as part of Open House Dublin presented by the Irish Architecture Foundation.
Now in its ninth year, it is part of a worldwide event aimed at connecting the public to their built environment and spatial experiences.
Visitors can experience a tour of the Casino at Marino and take a look inside a 350-year-old building, which is believed to be Dublin's oldest house.
They can also visit the headquarters of Airbnb in Ringsend or go inside the US Embassy in Ballsbridge.
Grand civic and historic buildings, representing a diversity of building styles and uses, along with a selected number of residential homes, are featured in this year's programme of more than 100 events.
Although events are free, places are limited for some buildings and advance booking is necessary.
