The 1890s marked the addition of a new larger refractor, the 28-inch Grubb in the Great Equatorial Dome. Because the new telescope was longer than the old Great refractor, the new dome had to be bigger; thus the famous "onion dome" that expands beyond the diameter of the turret was established. For the tricentennial, it was revitalized with a [[fiberglass|fibre-glass]] dome; the old one made of [[papier-mâché]] and iron had been taken down.

The telescope was installed by 1893, with 28-inch diameter glass [[Doublet (lens)|doublet lens]] made by Grubb from Chance of Birmingham glass.<ref name="Observatory-1897">{{Cite book|url=https://books.google.com/books?id=A1U3AQAAMAAJ&q=28+inch+grubb&pg=PR18|title=Observations Made in Astronomy, Magnetism and Meteorolgy|last=Observatory|first=Royal Greenwich|date=1897|publisher=H.M.

The [[William Lassell|Lassell]] two-foot reflector was a famous metal-mirror telescope that had been used to discover the Moons [[Triton (moon)|Triton]] (orbiting Neptune) and [[Hyperion (moon)|Hyperion]] (orbiting Saturn).<ref name="East meets west">{{Cite web|url=http://www.royalobservatorygreenwich.org/articles.php?article=1046|title=The Royal Observatory Greenwich - where east meets west: Telescope: The Lassell 2-foot Reflector (1847)|website=www.royalobservatorygreenwich.org|access-date=2019-11-28}}</ref> It was donated to the observatory in the 1880s, but was taken down in the 1890s.<ref name="East meets west" />

The 1890s also saw the construction of the Altazimuth Pavilion, completed in 1896 and designed by William Crisp.<ref>{{Cite web|url=http://www.royalobservatorygreenwich.org/articles.php?article=918|title=The Royal Observatory Greenwich - where east meets west: The Altazimuth Pavilion|website=www.royalobservatorygreenwich.org|access-date=2019-11-08}}</ref>
In 1898 the Christie Enclosure was established to house sensitive magnetic instruments that had been disrupted by the use of iron at the main facility.<ref>{{cite web | url=http://www.royalobservatorygreenwich.org/articles.php?article=974 | title=The Christie Enclosure | publisher=The Royal Observatory Greenwich | accessdate=6 April 2021 }}</ref>

The Observatory underwent an attempted bombing on 15 February 1894. This was possibly the first "international terrorist" incident in Britain.<ref>{{Cite book|

Bourdin died about 30 minutes later. It is not known why he chose the observatory, or whether the detonation was intended to occur elsewhere. The novelist [[Joseph Conrad]] used the incident in his 1907 novel ''[[The Secret Agent]]''.<ref>{{cite web|url=http://www.nmm.ac.uk/server/show/conWebDoc.413|title=Propaganda by Deed – the Greenwich Observatory Bomb of 1894|url-status=dead|archive-url=https://web.archive.org/web/20070930035329/https://www.nmm.ac.uk/server/show/conWebDoc.413|archive-date=30 September 2007|date=20 August 2015}}</ref>
