Irish expats are coming home to have their say on marriage equality, in some cases traveling thousands of miles to cast their ballot.
Voters have documented their journeys to the polling stations under the #hometovote hashtag in what has become a very emotional campaign.
Ireland has become the first country in the world to hold a referendum on whether to legalise same-sex marriage. Voters are being asked whether they agree with the statement: "Marriage may be contracted in accordance with law by two persons without distinction as to their sex."
However, votes need to be cast in person, so some of the three million eligible voters have had to come home to make their voices heard.
