It doesn't have to be big telescopes, there does not even have to be a telescope. It is called an observatory because it is a place where astronomical observations are made. Long before the first telescope was made there were observatories.
There are two very similar 10-meter telescopes at the W.M. Keck Observatory on Mauna Kea, on the Big Island of Hawaii.
An observatory is the name of a place that uses telescopes and other scientific equipment to study space and astronomy. The Mount Polamar Observitory in the west of the US is an iconic example. Today, Earth based observitories are supplimented by space telescopes.
I believe the name of the first telescope was called the "telescope." The word was created from the Greek tele = 'far' and skopein = 'to look or see'; teleskopos = 'far-seeing'.
An observatory is a place specifically designed for viewing stars and planets, usually equipped with telescopes and other scientific equipment. These facilities are often located in areas with minimal light pollution to maximize visibility of celestial objects.

Large telescopes have improved resolution over small telescopes and as such can gather clearer images of objects further away.
That telescope you are refering to is called a refracting telescope.

The largest telescopes that use visible light are reflector telescopes.
The big limitation was a lack of telescopes.
An observatory is a place where people view and study the sky and space, often equipped with telescopes and other astronomical instruments.
Telescopes are used to see things that are farther than we expected a thing to be.Telescopes are not only small.They can be big as well.
An "observatory".
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.

Depends on the business that works there... For instance, Asda is a big work place.
