Wellington Testimonial viewed from Islandbridge Junction.
Dublin has lit many of its most prominent architecture for St Patrick’s Day. The Wellington Testimonial in the Phoenix Park is believed to be the tallest obelisk in Europe. In the mid-19th century, when the railway line was built below the park, engineers were concerned that if the line passed to near the monument, it might undermine the massive structure. As a result the Phoenix Park tunnel is ‘S’-shaped, and swings to the west of the obelisk’s base.
