The church of the Holy Trinity (built in 1870) stands at the southern end of the ''rue d'Isly'' near the site of the demolished Fort Bab Azoun باب عزون. The interior is richly decorated with various coloured marbles. Many of these marbles contain memorial inscriptions relating to the British residents (voluntary and involuntary) of Algiers from the time of John Tipton, the first English consul, in 1580 (NB Some sources give 1585). One tablet records that in 1631 two Algerine pirate crews landed in Ireland, sacked Baltimore, and enslaved its inhabitants.
