Thomas Alloum was an English artist, painter topographical engineer, and member of the Royal Institute of British architects. He designed several build structures in London such as the Christ Church in Highbury in 1850 and the library of William Brown, as well as a lot of structures in Liverpool (1857-1860). In addition he designed the tower of Saint Leo de Garis church, near Tottenham in 1860. Most of his structures followed the Gothic style, and he was known by his several topographical works which were used to illustrate  travel books since 1820 when he traveled all over the United Kingdom and Europe. In 1834, he traveled to Istanbul and began to draw a lot of his paintings during his journeys through Anatolia, Syria, and Palestine. The outcomes of these journeys were published in 1838. In addition, he worked on church paintings in Minor Asia, which were published in two volumes by Robert Walsh. This paper examines the Turkish structures by Thomas Alloum during his stay in Turkey through several painting. In addition, it compares them to the remaining structures.
