The Browne Doorway was built in 1627 as the entrance porch to a townhouse on Abbeygate Street Lower, at its junction with St. Augustine Street. It was removed from that site in 1878 and re-erected as an entrance to the Eyre Square park in 1905, which means the stonework has effectively been in transit for longer than it stood in its original position. What makes the piece genuinely arresting is the density of information compressed into its carved surfaces: family names, heraldic arms, a Latin scriptural quotation, a Christian monogram, and a precise date, all arranged within an architectural framework that blends Italian Renaissance classicism with the decorative habits of Jacobean Ireland.

The doorway is structured around Tuscan columns with Ionic capitals set on tall pedestals with moulded diamond-shaped panels, supporting an architrave, a pulvinated frieze (that is, a convex, cushion-like band between the architrave and cornice), and a moulded cornice above. The arch itself is semi-circular in the Italian Renaissance manner, with a scrolled central keystone flanked by a carved quotation from Psalm 127:1: 'Nisi Dominus aedificaverit domum, in vanum laboraverunt, qui aedificant eam', meaning 'If the Lord does not build a house, then those who build it work in vain.' Above the arch, an oriel window projects outward with five lights divided by chamfered mullions and transoms. The apron below the oriel's canted sides is carved in low relief with stylised dragon-like creatures, though these are now very faint. The front panel names the owners in false relief: Martin Browne and Marie Linch, separated by the IHS monogram, itself enlivened by a square interlace cross rising from the H. Below the monogram, a mirrored cross separates the date numerals '16' and '27'. To the left are the arms and crest of the Browne family; to the right, the impaled arms of Lynch and Penrice with the Lynch crest above, all carved in high relief. This kind of armorial display was common among the merchant families of Galway in the early seventeenth century.

Beyond the carved names and the house's appearance on a mid-seventeenth-century Pictorial Map of Galway, where it is listed as 'The town-house and edifices of Mr. Martin Brown', nothing is known about Martin Browne or his wife Marie Linch. The doorway survives them entirely, now serving a public park rather than a private entrance, carrying its Latin admonition about labour and divine will into a context its carvers could not have anticipated.
