St Michael Bassishaw, or Basinshaw, was a parish church in Basinghall Street in the City of London,[1] standing on land now occupied by the Barbican Centre complex.

Recorded since the 12th century, the church was destroyed in the Great Fire of 1666, then rebuilt by the office of Sir Christopher Wren.

[2] A 14th-century parish priest of St Michael's, by the name of William, dug a ditch outside the church to assert his ownership and control of the right of way, but was obliged by the Corporation of London to fill it in again.

[2] John Burton, a mercer, and his wife Agnes were major contributors to the cost "as appeared by his mark placed throughout the whole roof of the Choir, and the middle Isle of the Church".

[3] From the fifteenth century, the dean and chapter of St Paul's Cathedral were patrons of the parish, meaning they appointed its clergy.

Fitch's work was unsatisfactory to the parish, and his columns were later described as "specimens of... jerry-building... made up of several sorts of materials and plastered over."

The steeple, probably designed by Robert Hooke, took the form of an octagonal drum surmounted by a lantern, from which emerged a trumpet-shaped cone.

The work revealed the weakness of the foundations, and in 1892 the church was judged unsafe and was closed, its parish combined with that of St Lawrence Jewry.

[2] Today the site once occupied by St Michael's lies beneath the courtyard of the Guildhall offices and the Barbican highwalk.

A plaster royal coat of arms from St Michael Bassishaw – the grandest of those in any Wren church – can now be found in the Guildhall complex.
