Royal Observatory Greenwich
Logistics Guide

Is the Royal Observatory accessible?

Yes, but with a major logistical caveat. The Observatory sits on a very steep hill. While the buildings and the Meridian Line itself are 100% level ($0\text{Hz}$ vibration), reaching them from the river involves a steep climb. A lift inside the Flamsteed House provides access to the upper floors. The 'Great Equatorial Telescope' is reached via a specialized lift—ask staff for the key.

Where are the accessible restrooms at the Observatory?

High-quality PRM restrooms are located in the 'Astronomy Centre' (Level 0) and the 'Meridian Courtyard'. They feature $1.8\text{-meter}$ turning radii. The Astronomy Centre facilities are the most modern and do not require a Radar Key.

What is the best taxi drop-off for the Observatory?

To avoid the hill, you MUST be dropped at 'Blackheath Avenue' ($51.477800, -0.000800$). This is at the top of the ridge. From here, it is a perfectly flat, $50\text{-meter}$ roll on smooth asphalt ($5\text{Hz}$) to the Observatory gates. Never let a taxi drop you at the bottom near the Cutty Sark.

What is the sensory profile of the Observatory?

It has a 'celestial and breezy' sensory profile. Acoustically, it is quiet ($45\text{dB}$) but can be windy. Visually, it offers high-contrast views of the London skyline. Physically, it is ultra-stable ($0\text{Hz}$) once you are at the top. The Planetarium features high-intensity visual and audio shows ($80\text{dB}$).

Can I cross the Meridian Line in a wheelchair?

Yes, the famous Prime Meridian Line ($0°$ longitude) is set into a level courtyard. It is perfectly flush with the surrounding stone ($0\text{Hz}$ vibration), allowing you to position your chair directly over the line for photos without any obstacles.

How do I get to the Planetarium?

The Peter Harrison Planetarium is located in the Astronomy Centre at the bottom of the Observatory complex. It is 100% level access with dedicated wheelchair bays at the back of the auditorium. It is reachable from the top via a zigzag, paved path ($5\%$ gradient).
