The Western Wall most tourists see — the broad outdoor plaza where people press notes into the ancient stones — is only a fraction of the original structure. What stands exposed in the open air is 57 metres of wall. The full Herodian Western Wall is 488 metres long.
The rest is underground.
The Western Wall Tunnels are the excavated passage that runs along the wall’s entire western face, burrowing beneath the Muslim Quarter of the Old City. They are one of Jerusalem’s most extraordinary archaeological sites and one of the most popular paid experiences in the country — and yet many visitors skip them simply because they don’t know they exist.
This guide covers what you’ll see, how to book, and what to expect from your 60–70 minutes beneath the city.
What the Tunnels actually are
King Herod the Great undertook one of antiquity’s most ambitious building projects when he expanded and rebuilt the Temple Mount in the first century BCE. To create the vast platform visible today, he filled in valleys, built massive retaining walls, and constructed a stone esplanade large enough to hold hundreds of thousands of pilgrims.
The Western Wall is one of those retaining walls. Built from massive limestone blocks quarried in the Judean hills, it rose to an original height of around 32 metres. After the Romans destroyed the Temple in 70 CE, the city was rebuilt over the rubble. Centuries of construction — Byzantine, Umayyad, Crusader, Mamluk, Ottoman — buried the lower courses of the wall under the accumulated depth of 2,000 years of occupation.
The Western Wall Heritage Foundation and archaeologists have spent decades excavating the buried sections. The Tunnels follow that original Herodian-era wall northward, exposing the full structure from its ancient foundation courses to the medieval buildings constructed against it.
What you see underground
The Herodian Street
Immediately below street level lies a Hasmonean-era aqueduct channel and, adjacent to it, a Herodian-era street that ran along the base of the wall in the first century CE. The street was buried when the Roman armies backfilled the area in 70 CE. Walking along it feels genuinely anachronistic — the paving stones are worn by foot traffic that stopped almost two millennia ago.
The Western Stone
At the base of the Herodian wall, roughly one-third of the way along the tunnel route, sits the Western Stone. It measures approximately 14 metres in length and is estimated to weigh around 570 tonnes — one of the largest building blocks in the ancient world still in its original position.
No cranes or modern machinery existed when this stone was quarried, shaped, and placed. Herod’s engineers used a system of earthen ramps, sledges, and thousands of labourers. The sheer mass of the stone becomes real when you stand next to it.
Warren’s Gate
The Tunnels pass a sealed archway known as Warren’s Gate — named for the British explorer Charles Warren, who first documented it in 1867. It was one of the original four gateways leading from the Herodian street directly into the Temple Mount.
The gate has been sealed since the early Islamic period, when the Muslim Quarter was built above it. From inside the Tunnels, you stand within metres of the Temple Mount’s western edge. For observant Jewish visitors, this proximity — geographically closer to the site of the Holy of Holies than any other accessible point — carries profound significance.
The Hasmonean Aqueduct and Cistern
Deeper into the Tunnels, the route incorporates the remains of earlier water systems: a Hasmonean-period water channel (pre-dating Herod by a century) carved through the bedrock, and in some sections, the edge of the Struthion Pool — a massive ancient cistern later covered by the Roman Forum and now partially visible beneath the Convent of the Sisters of Zion.
The layering of water engineering from three different civilisations is a quiet illustration of how Jerusalem has been continuously inhabited, rebuilt, and adapted over millennia.
Booking your visit
Book through the official site or a licensed operator
The Western Wall Heritage Foundation manages the Tunnels. Their booking portal — english.thekotel.org — lists available tour slots in English. Tickets purchased directly are the most affordable option.
Licensed tour operators on GetYourGuide and Viator also hold blocks of timed entries. These cost more but offer benefits: a professional English-speaking guide (rather than relying on the standard audio-guided slot), smaller group sizes, and the ability to combine the Tunnels with the Western Wall plaza, Jewish Quarter, or Old City walk in a single guided experience.
Timing: book weeks ahead for morning slots
Morning slots (09:00–11:00) sell out first, especially on Sundays and during peak season (Passover, summer, Sukkot). If you are visiting Jerusalem on a tight itinerary, secure a Tunnels slot before you finalize your travel dates.
Mid-afternoon slots are less pressured and are a good fallback if your preferred morning slot is full.
What the ticket includes
All Tunnels visits include a guided experience — you cannot walk through independently. English-language audio guides are available for self-paced visits at certain slots; dedicated English-speaking human guides are available for group and private tours.
The experience: what to expect on the day
Arrival and security
Enter through the Western Wall Heritage Foundation entrance in the Jewish Quarter, adjacent to the Western Wall plaza security checkpoint. Present your booking confirmation. Security screening applies (same level as the outdoor plaza). Arrive 10–15 minutes before your tour departure.
The tour itself
Tours run for 60 to 70 minutes. The route is entirely underground and follows a linear path northward along the wall. You cannot linger or explore independently — the guided format keeps the group together and moving.
The underground atmosphere is cool (a welcome break from Jerusalem’s heat in summer) and well-lit throughout.
The exit: Via Dolorosa
A detail that catches many visitors off-guard: you exit onto the Via Dolorosa in the Muslim Quarter, not back through the Jewish Quarter entrance where you began. Security staff accompany groups for the first few metres.
You emerge near Station II of the Via Dolorosa, a short walk from the Austrian Hospice and a natural entry point into the Christian Quarter. The Muslim Quarter spice market surrounds you immediately. This makes the Tunnels a natural pairing with a Via Dolorosa walk or a visit to the Church of the Holy Sepulchre.
Practical tips
Mobility: The Tunnels involve uneven stone surfaces and some stairs. The route is not accessible for wheelchairs or those with significant mobility limitations.
Dress code: The same dress code as the Western Wall plaza applies — covered shoulders and knees for both men and women. Bring a scarf or layer if visiting in summer.
Photography: Photography is permitted inside the Tunnels. Bring a phone or camera; there is no flash restriction in the open tunnel sections. Some particularly sacred points near Warren’s Gate see guides ask for cameras to be lowered out of respect.
Combined visits: The Tunnels pair naturally with the adjacent Western Wall plaza (plan this before your Tunnels entry, since you’ll exit elsewhere), the Jewish Quarter’s Cardo and Broad Wall, and the Via Dolorosa. A half-day Jerusalem morning that covers all three is very manageable.
Who should visit
The Western Wall Tunnels reward visitors who want to understand Jerusalem rather than simply see it. If you are content with the outdoor Wall and a quick photograph, the Tunnels add significant time and cost. If you are drawn to the archaeology of the city — to standing at the foundations of something that shaped human history — the Tunnels are among the most affecting things you can do in Israel.
For Jewish visitors with a connection to the Temple Mount’s significance, the underground proximity to Warren’s Gate is reason enough.
For Christian pilgrims walking the Via Dolorosa, emerging from the Tunnels into the Muslim Quarter adds an unexpected dimension: a literal transition from the deep Herodian past to the street where tradition places Jesus’s final walk.
