The Jeanie Johnston is an accurate replica of a famine ship which sailed from Ireland to America around the 1850's.
It is currently docked in Dublin, Ireland where you can tour it and view it as a "ship musuem".
See here for more information.
Recently for St Patrick's day 2013 it was lit up green - like a lot of Dublin landmarks/buildings were.
Here are two photographs I took of it:
On this photograph I put a green filter/effect on it. This means that the camera removes colour and just highlights any green in it.
Pretty cool eh?!
