The Holy Trinity Cathedral in Karachi is the oldest and largest Protestant cathedral in the city, situated in the Civil Lines area

The building was completed over a span of three years and was officially consecrated for public worship on 18th March 1855.

At the time, it was among the largest buildings in Karachi, with its tall tower visible from a considerable distance

The cathedral was designed by Captain John Hill of the Bombay Engineers in the Italian architectural style.

The Holy Trinity Cathedral in Karachi was designed in the Florentine Renaissance style, influenced by Italian ecclesiastical architecture.

Among the most refined features of the church are the stained glass windows located at the back of the apse

 These three elongated vertical windows are housed within semi-circular arches, with the central window slightly taller than the two flanking ones.

The interior of the cathedral is designed as a tall, grand hall. The roof is supported by a series of large semi-circular arches that run along the length of the hall, each resting on substantial circular columns.

The stained glass, dated 1879, is attributed to the artist H. Hughes of London and is recognized as one of the cathedral’s most distinctive and beautiful architectural elements.

The Holy Trinity Church remains one of the most important chruches of Karachi
