Royal Ulster Rifles Museum is a must for anyone interested in military history. Ulster was heavily affected by both world wars suffering enormous losses in battles of the First World War, particularly the Somme, and sustaining the heaviest Blitz damage of any UK region outside London in the World War II. Artifacts from the uniforms and weapons of the Royal Ulster Rifles and its predecessor foot regiments are collected here, charting its impressive history through the wars that have shaped the 20th Century. Admission is free.

Nestled in a corner of the iconic Botanic Gardens, the Ulster Museum is one of Belfast's most prestigious establishments with a spectacular collection art, ethnography and archaeology sourced from all across the globe. Formally established in the year 1929, this elegant four-story structure is located within walking distance of Queen's University's plush campus. The main highlights of the museum include riches recovered from the wreck of a Spanish Armada ship salvaged off the Giant's Causeway. Its top-floor gallery displays a series of exquisite British and Irish artwork.

The North Down Museum is behind Bangor Castle in Castle Park. The centre is the most visited small museum in the country. Impressive displays of Bangor history, from the early Christian monasteries to the 1950s holiday, are presented with the aid of artifacts and audio-visual equipment. Special activities are organized for kids, and if they start to play up, you can always take them to the observation beehive and tell them you've got the key! Relax in the cafe and enjoy coffee or ice cream. The cafe doubles as a recital room, and hosts the annual Aspects Festival of Irish writing.
