Tomorrow marks a year to the day the same-sex marriage referendum was passed in Ireland.

People have been getting all nostalgic and sharing some very lovely thoughts and memories on Twitter, under the hashtag #MarRefMemories. It's thought that some of the couples who got married this year will gather at Dublin Castle, where the news was officially announced, to celebrate. If you need inspiration for how to mark the occasion, check out our list of things to do here. Also, have a look at #MarRefMemories, it's just fab.

Great memories of this time last year. Special thanks to everyone who made the impossible possible #marrefmemories pic.twitter.com/NoupKrj8ik
