Winter solstice sunrise

These are the first images to show the sunlight shining through the house taken on the morning of the 23rd June, 2007, the day after the winter solstice.

Research has shown that Elizabeth Bay House is precisely oriented to the position of the sunrise at the winter solstice, the shortest day of the year and the moment when the sun rises at it's furthest point north on the horizon.

Shortly after sunrise on this day, when the sun is just above the horizon, the central axis of the house is evenly flooded with sunlight from the front door to an area of the cliff face at the rear of the property. This dramatic effect, as the architraves and stone flooring along the central corridor are evenly illuminated, lasts for less than a minute. For over two weeks before and after the winter solstice, the effect may be observed with varying luminance and duration as the elevation of the sun and its position on the horizon gradually change.

Elizabeth Bay House was completed in 1839. It's design is attributed to architect John Verge on the basis of his office ledger. The house's owner, Colonial Secretary, Alexander Macleay was well versed in matters of taste, architecture and landscape design. There appears to be no direct reference to this aspect of the house's siting in early documentation.

The creation of the site of Elizabeth Bay House involved removing the foot of the Darlinghurst ridge after nine years deciding on the location. The entire plan of the house and its kitchen block at the rear (demolished in 1927) emphasise the axis of the central corridor. A straight viewing line occurs through the doorways aligned along it and the house's staircases are set to one side. The height of this corridor above sea level must also have been precisely determined to properly accommodate the sun's rise over the landmass to the east.

Macleay had the scientific interest, contacts, and the time required for such a rational and ordered astronomical alignment. The symmetry and precision of this annual occurrence certainly sit well within the house's more celebrated design elements.
