Shandon comes from the Irish Sean Dún, meaning old fort. A medieval church stood near here from at least 1199, when it was mentioned in the decretals of Pope Innocent III as St Mary on the Mountain. That church survived until the Williamite wars, when it was destroyed in the 1690 siege of Cork. A replacement was built in 1693 at the bottom of what is now Shandon Street, but the population was growing and the location was awkward. In 1722 construction began on a new church, on the old high ground, dedicated this time to St Anne. The building was finished in 1726. In 1772 the church attained full parochial status and the Reverend Arthur Hyde - the great-great-grandfather of Douglas Hyde, who would become the first president of Ireland - was appointed its first Rector.

St Anne's is the architectural reason Cork's civic colours are red and white. The walls were built from two materials: red sandstone salvaged from the ruins of the nearby Shandon Castle, and limestone taken from the derelict Franciscan Abbey that once stood on the North Mall. The result is a tower that looks like a deliberate stripe pattern, with red sandstone on two sides facing the river and pale limestone on the other two facing the city. The colours became Cork's. A nineteenth-century antiquary, Thomas Crofton Croker, recorded a rhyme attributed to the eighteenth-century Catholic preacher Father Arthur O'Leary that called out exactly this dual character. The rhyme is still cited locally. Walk around the tower and the colours rotate as you move; the building changes complexion depending on which face is in front of you.

The eight bells of Shandon were cast in Gloucester, England by Abel Rudhall in 1750, shipped across the Irish Sea, hauled up the tower, and first rung on 7 December 1752. The largest weighs a little over 1.5 tons. To reduce vibration on the old structure, the bells were installed in fixed position rather than swinging, and they are played from below using an Ellacombe apparatus - a console of ropes that lets a single ringer chime them in sequence. Each bell bears its own inscription in eighteenth-century English, ranging from a benediction ("Health and prosperity to all our benefactors") to a memento mori ("I to the Church the living call and to the grave do summon all"). The bells were recast in 1865 and again in 1906. They remain the bells that Francis Sylvester Mahony's nineteenth-century song The Bells of Shandon immortalised, which is why so many Corkonians abroad still tear up at the sound.

The clock on the tower has four faces, one looking in each cardinal direction. The walls of the tower are two metres thick, and the four sets of hands are driven by a single mechanism deep inside the structure. The wind catches the hands differently on each side. The light catches them differently too. Depending on the angle of the viewer and the strength of the gust, the time the clock shows on one face never quite matches the time on the others. Corkonians began calling it the Four Faced Liar long before the maintenance issues that stopped the clock in 2013. Repair funding was agreed in May 2014, and the clock restarted in September 2014. It still lies, of course. The lying is the point. A McOsterich family helped design the tower, and to this day they hold one privilege: whenever any member of the family marries, anywhere in the world, the bells of Shandon ring out in their honour.

On top of the Pepper Pot adornment a giant copper salmon turns in the wind, the city's weather vane representing the fishing of the River Lee. The Cork band Five Go Down to the Sea? memorialised it in their song There's a Fish on Top of Shandon (Swears He's Elvis), which is exactly as Cork an idea as it sounds. Inside the church, the christening font is older than the building. It dates from 1629, a relic from the church destroyed in the 1690 siege of Cork, and it bears the inscription "Walter Elinton and William Ring made this pant at their charges." A pewter bowl dated 1773 sits within it. The font has now baptised people in three different churches across four centuries, the oldest continuously-used object on a site where everything else - the fort, the medieval church, the 1693 replacement - has been swept away.
