The post office is located in a new stand-alone premises located in the Douglas Court Shopping Centre, which is 100 yards away from the former premises.
Commenting on the official opening, Pat Cremin, An Post’s Business Development Manager for the Cork region said:
"We are delighted to be back in action in Douglas.
"Our new office will offer all that’s best in the modern post office to regular customers and also a new generation of post office users".
Mr Cremin said the new office provided all long-established post office services, along with a range of popular financial products including the An Post Money Current Account, Credit Card, loans and Foreign Exchange.
Douglas residents, including pensioners, have been forced to travel to Blackrock for services since their local post office closed following a major fire in the car park of Douglas Village shopping centre.
From today, however, Department of Employment Affairs and Social Protection customers currently accessing their payments through Blackrock post office will now transfer back to Douglas post office.
The post office will open from Monday to Friday 9:00am to 5:30pm, and Saturday 9:00am to 1:00pm.
Earlier this month, traders at the fire-damaged Douglas Village Shopping Centre were asked to return their keys to their businesses, so that builders can assess the units.
Centre manager Bartosz Mieszala toldthat the centre is on course to reopen this summer.
