The new government offices on the corner of Union Street and the Parade has opened to the public for the first time.
Islanders can now visit the £91m building, as the 'customer hub' opened at 8:30 am on Monday (9 December).
La Motte Street and Eagle House closed their doors for the last time at 5:00 pm on 6 December.
The HQ is the new home of Employment, Social Security and Housing, formerly known as Customer and Local Services.
It provides the services previously delivered at Philip Le Feuvre House and is now the destination for anyone wanting a registration card, needing information about pensions, Income Support, Income Tax, Social Security contributions, and benefits - including health, long-term care and parental.
It is also the venue for Business licensing and support, Student Finance, housing advice, and guidance from Planning and Building Control.
Children's Services have also moved to Union Street from Liberte House, but Child and Adolescent Mental Health Services (CAMHS) remains at Liberte House.
The government says the new building has been designed to be as accessible as possible - with facilities for people who are sight or hearing impaired.
There is better provision for those with poor mobility, and somewhere to change and care for children.
Union Street is open to customers from 8.30am to 5pm Monday to Friday.

The last civil servants have moved in to the new building this week. It is on the site of the former Cyril Le Marquand House.
It brings together government staff from 12 buildings into one six-storey block.
The former Chief Minister, John Le Fondré, said the move would save the government £7 million annually by reducing the number of offices from 21 to six.
Last month, the States Assembly approved the £91m purchase of the new office block from developers Dandara.
