Finnish architect Marco Casagrande and Alaskan sculptor Martin Ross together with Tamkang University (Taiwan) department of architecture students created 8 Trojan Rocking Horses to attack Taipei City. During the offensive campaign to gain control of the city the Taipei citizens wrote down their dreams and wishes and placed them into the welded steel horses approaching the city center to eventually siege the Taipei City Hall.
The campaign culminated in delivering Mayor Ma Ying-jeou (馬英九) the keys of his city - the citizen data in the belly of the horses. The work became a direct cross disciplinary action according to Fritz Lang's maxim: THE MEDIATOR BETWEEN THE HEAD AND THE HANDS MUST BE THE HEART.
2004年台北市政府文化局策動「台北城市行動」，其中參與本場活動的芬蘭建築師馬可 ·卡薩格蘭（Marco Casagrande）和美國鑄鐵藝術家馬丁·羅斯（Martin Ross）與淡江大學建築系碩士班學生共同合作創作「鐵馬贖城記」。建造八座鐵馬，從 城市邊緣收集城市居民對與台北市的夢想和期許，以各種方式用血汗勞力和愛的訊息進攻台 北城。影片最後由當時台北市長馬英九親自取出這些信件，傾聽部分市民的心聲。
