[2] The second definitively recorded chaplain, Dr Samuel Barton, was expelled in 1683, at the behest of the Portuguese Inquisition.

[6] The erection of a church building and the setting out of a churchyard for Protestant burials, however, were even more contentious than the mere appointment of a chaplain.

[7] By a treaty of 1810 the Portuguese Prince Regent (then exiled, by the Peninsular War, in Brazil) permitted British residents to erect their own churches.

This permission was on the proviso that the external appearance was of private dwelling houses and that no bells were rung to announce the services.

[10] The architect was Joaquim da Costa Lima Sampaio, who also designed the palace that is now the Soares dos Reis National Museum.

These were abolished by the British Government in 1865, but the subscriptions (for the same amount as the pew rent that had hitherto been in place) remained as the qualification for attending general meetings.

The subscriptions were only finally abolished in 1939, as abolition was one of the conditions imposed by Canon Johnston for accepting the chaplaincy.

It was made by James Powell and Sons of London and depicts the Bread of Life and the True Vine.

Oldknow visited Oporto in 1855, and was shocked by what he saw, particularly the presence of British Nonconformists ("Presbyterians, Independents and Wesleyans") in the congregation.

[26] An early service of Holy Communion (a High Church introduction) commenced on a monthly basis in 1890, and, by 1931, had become weekly.

[27] Other High Church introductions in 1931 included a surpliced choir[28] and two candlesticks on the altar, to accompany the cross that had been placed there in 1906.

[34] To celebrate the rebuild, a violoncello and organ recital was given early in 1938 by the Portuguese cellist Guilhermina Suggia and the organist Cyril Langley Salmons.

[35] Further restoration work was undertaken in 1957, but in 1974 it was decided to scrap the pipe organ, and replace it with an electronic instrument, purchased from Heyliger's of the Netherlands.

[37] There is some historic record of an early cemetery for Protestants in Oporto, but this was suppressed by the Inquisition by at least 1719, and no evidence of it remains, nor any certainty of its exact location.

[40] By the late 18th century the attitude of the Portuguese authorities had moderated sufficiently to allow the British merchants to acquire land for a cemetery.

[52] Notable burials include Charles Birdwood, Vice-Consul, Oporto (d 1957), John Delaforce CBE, port wine producer (for Delaforce, acquired by Taylor Fladgate in 2001)[53] and historian of the Porto British community, and Alfred Wilby Tait, Baron de Soutellinho, port wine merchant.

All of the names of the merchants who signed a resolution in 1815 to draw up a plan for the chapel were connected with port wine.
