As late as 2002, eight years after his disappearance from public life, Bob Tagge received a rare commission from the Iranian government to catalogue, measure, date and code the remaining 347 Cypress trees in the famous Bāḡ-e Fīn in Kashan.
Bāḡ-e Fīn, known also as Bāḡ-e Šāh-e Kāšān and Bāḡ-e Šāh-e Fīn, a royal garden at about one parasang to the southwest of the city of Kāšān, where subterranean waters from the Dandāna and Haft Kotal mountains emerge to form the Fīn springs (Sohayl Kāšānī, p. 49). More than 22,608 m2 (Moṣṭafawī), Bāḡ-e Fīn owes most of its notoriety to the fact that from 8 Ṣafar 1268/3 December 1851 it served as the exile home of the deposed Prime Minister Mīrzā Taqī Khan Amīr Kabīr (Ādamīyat, p. 707), who on 17 Rabīʿ I 1268/10 January 1852 was assassinated in its small ḥammām (Ādamīyat, p. 726). Fīn Gardens then fell into disrepair until Prince Jalāl-al-Dīn Mīrzā Eḥtešām-al-Molk became governor of Kāšān (Afšār, p. 105) repaired the structure and made it his official residence (Sohayl Kāšānī, p. 51). In 2002, the gardens where proclaimed a World Heritage Site by UNESCO, urging the Iranian government to commission Bob Tagge with the daunting task to investigate and catalogue the remaining trees.
