Late Bar at The Barrel & Castle

At The Barrel & Castle · Linenhall Street, Castlebar, Co. Mayo, F23 DE20

The Barrel & Castle bar and late venue in Castlebar

What to Expect

The Barrel & Castle is a two-level brasserie-style bar and restaurant on Linenhall Street in Castlebar that opened in March 2024 after a full refurbishment. It seats over 200 guests and includes a heated beer garden, and while it runs as a dining venue through the week, it shifts into a late bar every Saturday, staying open until 2am rather than closing at the usual weeknight time. Live music is a regular weekend feature across the venue, and the combination of a heated outdoor space with an indoor late bar gives visitors somewhere to move between depending on the weather and the size of the crowd.

Good to Know

  • Late bar runs every Saturday, open until 2am
  • Standard hours the rest of the week: Monday to Thursday 12:30pm to 11:30pm, Friday 12:30pm to 12:30am, Sunday 12:30pm to 11pm
  • Live music features most weekends, though the specific acts are announced closer to the date rather than published in advance
  • Food is served daily from 12:30pm to 8pm for anyone eating before the late bar starts
  • Heated beer garden available, useful for overflow when the indoor room is busy
  • Seats over 200 guests across its two levels, making it one of the larger venues in Castlebar town
  • Can be booked privately for celebrations and events outside its normal late bar nights
  • This is a weekly recurring night, not a single date; the date above marks the next Saturday opening

As one of Castlebar’s newer venues, having opened in March 2024, The Barrel & Castle sits alongside older established late bars in the town, giving visitors another option within easy walking distance of the Linenhall Arts Centre and the Mall. Its size, seating over 200 across two levels, makes it one of the bigger rooms in Castlebar to shift from a dinner crowd earlier in the evening into a Saturday late bar, which suits people who want to eat before heading out rather than starting the night cold at a dedicated nightclub.
