The General Post Office (GPO) Museum: Dublin's 1916 Headquarters

The General Post Office (GPO) on O’Connell Street is not just a place to buy stamps. While the front half of the building remains the operational headquarters of An Post (the Irish postal service), the eastern side houses the GPO Museum (formerly known as GPO Witness History).

In April 1916, a group of Irish rebels seized this building, barricaded the doors, and declared an independent Irish Republic. The ensuing battle—the Easter Rising—left the GPO in ruins and changed the course of Irish history. Today, the museum offers a detailed, objective look at those events through interactive exhibits, original artifacts, and immersive audiovisual displays.

Whether you are tracing your family history, studying 20th-century European conflicts, or simply walking down O’Connell Street, understanding the GPO is central to understanding modern Ireland.

Who Should Visit the GPO Museum?

The GPO Museum is highly focused on a specific six-day period in 1916. Here is how to approach your visit based on your travel style:

• History Buffs: You will want to allocate at least 90 minutes to two hours here. The museum does an excellent job of explaining the complex political factions (Irish Volunteers, Irish Citizen Army, Cumann na mBan) that united for the Rising. To get the full picture, pair this visit with a trip to Kilmainham Gaol, where the leaders were subsequently executed.
• Families with Older Children: The museum is highly interactive. Touchscreens, a Morse code station, and a central immersive film keep teenagers and older children engaged. However, the subject matter involves war, execution, and civilian casualties, which may require context for younger kids.
• The Time-Poor: If you only have 45 minutes, you can still get value from a standard entry ticket. Focus on the central semicircular film experience and the original Proclamation document, then take a quick walk through the working post office hall to see the architecture.

5 Architectural & Cultural Highlights

The GPO was designed by Francis Johnston and opened in 1818. It was one of the last great Georgian public buildings erected in Dublin. When you visit, look out for these specific details.

1. The Greek Revival Portico & Bullet Holes

Before you even enter the museum, stand on O’Connell Street and look at the building’s facade. The portico features six massive fluted Ionic columns. If you look closely at the stone pillars, particularly the ones on the outer edges, you can still see the pockmarks and gouges left by British bullets and shrapnel during the 1916 bombardment. The facade was one of the few parts of the building to survive the resulting fire.

2. The Statue of Cúchulainn

Inside the main public hall of the working post office (which is free to enter), you will find a bronze statue of the mythical Irish warrior Cúchulainn. Created by sculptor Oliver Sheppard in 1911, it was moved to the GPO in 1935 as the official memorial to the men and women who died in the Easter Rising. The statue depicts the warrior tied to a pillar so he could die standing up—a direct parallel to the rebels’ last stand.

3. The Original Proclamation of the Irish Republic

Inside the paid museum area, you will find one of the few surviving original copies of the Proclamation of the Republic. This document was read aloud by Patrick Pearse outside the GPO on Easter Monday, 1916, officially starting the rebellion. The museum explains the rushed printing process; if you look closely at the document, you can see where the printers used different fonts and mixed typefaces because they ran out of matching letters.

4. The Immersive Audiovisual Film

The centerpiece of the museum is a semicircular theater that plays a 15-minute film. Rather than a dry documentary, the film uses dramatic reenactments, original photographs, and intense sound design to put you inside the GPO during the siege. It effectively conveys the chaos, the deafening noise of the HMS Helga shelling the city from the River Liffey, and the eventual realization that the rebels had to evacuate the burning building.

5. The Inner Courtyard Memorial

The museum tour concludes in the inner courtyard, an open-air space that offers a quiet moment of reflection. Here, a modern sculptural memorial lists the names of the children who died in the crossfire during the 1916 Rising—a poignant reminder of the civilian cost of the conflict, which is often overshadowed by the military history.

Ticket Options: Independent vs. Guided Tours

You have two main ways to experience the GPO: exploring the museum independently at your own pace, or joining a guided walking tour that uses the GPO as a focal point for a broader 1916 history lesson.

Which Should You Choose?

Keep Planning: If you are interested in Ireland’s broader struggle for independence, consider adding a visit to Dublin Castle, which served as the seat of British rule in Ireland for 700 years.

Logistics & Transit Directions

The GPO is impossible to miss. It takes up a massive block on the western side of O’Connell Street, Dublin’s main thoroughfare, right next to the Spire (the 120-meter tall stainless steel monument).

• Address: O’Connell Street Lower, Dublin 1.
• By Luas (Tram): The Green Line stops directly outside the building at the O’Connell - GPO stop. If you are on the Red Line, get off at Abbey Street and walk two minutes north. Read our Luas Guide for ticketing details.
• By Bus: Almost all cross-city bus routes pass through or terminate near O’Connell Street. Routes 1, 11, 16, 46A, and 155 all drop you within a three-minute walk.
• On Foot: The GPO is a 5-minute walk north of the River Liffey (O’Connell Bridge) and a 10-minute walk from Trinity College.
• Entrance: Do not queue at the postal counters. The entrance to the museum is located inside the main portico, but off to the right-hand side (eastern side) of the building. Look for the “GPO Museum” signage.

Local Survival Tips for the GPO

1. Avoid the School Crowds Because of its significance to the Irish curriculum, the GPO Museum is heavily visited by domestic school groups, particularly on weekday mornings between 10:00 AM and 12:30 PM. To avoid the noise, book your entry tickets for 2:00 PM or later.

2. Look Up in the Main Hall Even if you are just passing by, walk into the main public post office hall. The ornate, coffered ceiling was meticulously restored after the 1916 fire. It is one of the most beautiful public interiors in Dublin, and it costs nothing to look at.

3. Combine with Moore Street When the GPO caught fire during the Rising, the rebel leaders tunneled through the walls of the houses on nearby Moore Street to escape. After your museum visit, exit the GPO, turn right onto Henry Street, and take the first right onto Moore Street. It is a historic market street where the final surrender order was given.

4. Coffee Nearby The GPO has a small café in the courtyard, but for better coffee, exit the building, cross O’Connell Street, and head down North Earl Street to Vice Coffee Inc (located inside Wigwam). It serves some of the best specialty coffee in the city center.

Where to Stay Near the GPO

Staying near O’Connell Street puts you right in the middle of Dublin’s transit network, making it incredibly easy to reach the airport, the ferry port, or any of the city’s main attractions. The area immediately north of the GPO can be quite busy and noisy, so look for hotels on the side streets or just south of the river.
