An interesting small (4 sections) museum in an old building with kind respectful staff. It is free on the first Saturday of the month. It is inside a very old building when you walk you can feel the woods cracking underneath your feet. It has a collection of ancient fossil representation, and one part is for the remaining of human civilization in Portugal, including bones, skull, and ruins of utensils used by ancient people. In the last part of the museum there are different types of stones and salt formations. I was alone on my visit and no one else was there so i could take my time slowly visiting every where and it take at least one hour to look at everything. Unfortunately they don’t have a shop to be able to get some memories just a few postcards. The overall being old the building will highlight the ancient atmosphere of the museum. However from technical point of view i think the building needs a renovation at least at some points. The descriptions were mainly Portuguese but like almost 10% of descriptions were translated, so i couldn’t use fully from my visit (though its my fault not knowing Portuguese) I recommend this museum if you are in the field of sciences and or living in Portugal and want to have a nice educational day.

Fantastic room to watch a classical music concert.

Must be a great place for geography buffs. 98% or so of all the info is in Portuguese only so without the guide, not too interesting / self-evident. Nevertheless we spent about 1.5 hr on the premises and were the only 2 visitors at the time. To get to the museum you should ascend to the 2nd floor; not too obvious either.

If you are the least bit interested in geology, paleoanthropology, or paleontology please visit this museum. It has SO much to look at! It's curated to give you glimpses at many many many artifacts. It's amazing. And if you're kids are into Dinosaurs, then there are enough bones and fossils here to make their heads spin. Love this museum. Will be back next visit. Highly Recommend.

This is a place for geology. The exhibition is diverse in many eras. Also it represented the geological history in Portugal. Really a great place for expanding knowledge. Recommended.

If you are nearby it is compulsory to visit the Geological Museum of Portugal. It is located on the 2nd floor of the Academy of Sciences of Lisbon. Visits on the first Saturday of each month are free of charge. Normal entrance fee 5 euros for adults and 2.5 euros for children upto 18 years old and seniors.

Highly recommended!! What a gem! The collection of fossils and rocks here is massive!!! Specimens are very nicely sorted and displayed! Totally loved the dinosaur bone fossils!

Fascinating library hidden between behind the Principe Real district. An academy with a history to discover.

This place is very beautiful. It is an old, well conserved house. I didn't go to the museum itself, but to a cámara concert that was delightful. The sound was impecable. If you have the chance of visiting or finding an event taking place here, you must make time for it.

First rate museum, if rather dated in presentational style. Excellent fossil and mineral collections that are actively used in study.

Beautiful museum, full of incredible artifacts, fossils and more! It goes far beyond geology, to include evolution (including humans), scientific history, and art. Well worth the visit!

Beautiful place.

The main hall and the whole building indeed are worth a visit.

Very nice museum with a wondurful historic library and interesting exhibition of cientific and historical items. We enjoyed our private guided tour, thanks again to the lady who explained us about the exhibition and the history of this museum.

The Lisbon Academy of Sciences was founded on December 24, 1779, with the consent of Queen D. Maria I. The main responsible and mentors for the realization of this project were, above all, the 2nd Duke of Lafões, D. João Carlos de Bragança, the first President, and the abbot José Corrêa da Serra, the first Secretary-General, who, knowing the European counterparts, conceived a similar institution for Portugal. It has a magnificent library and important conferences are held in its main hall.

(Translated by Google) I recommend the visit. Kind attention. Splendid buildings. Small but interesting ethnographic collections from Brazil. (Original) Recomiendo la visita. Amable atención. Edificios espléndidos. Pequeñas pero interesantes colecciones etnográficas de Brasil.

Most marvelous trip back into time, to the age litterates spend weeks or months to write books by hand. One of the largest ancient books collections i have ever seen.

You can not walk in and visit this place apparently you have to book an appointment. This doesn't say this on the website or outside on the sign. Do not recommend! Rude staff. No help given. Don't waste your time!

Historic place very well preserved.

(Translated by Google) Very beautiful gym, it is worth a visit from the inside, the outside is like all public buildings. (Original) Academia muito bonita, é digna de uma visita pelo interior, a nível exterior está como todos os edifícios públicos.

The museum is relatively expensive for what you're getting. 5 euros for spending about 10 or 15 minutes inside is not really worth it. It's only good if you're truly interested in geology. If you're going for the fossils and bone specimens you don't need to spend much more time in here. It is a pity that most, if not all, plaques and descriptions are exclusively in Portuguese.

Good display of artefacts but no longer accepts Lisboa Card

Underrated little museum. Should be a must for families. Very organized but mostly in Portuguese and some English. I recommend.

Beautiful library, used for great classical concerts.

Cheap, not crowded ( I was alone ) it is worth the visit. Some very impressive pieces. 150 to 500 millions years old impressive....

The best place to see fossils in Lisbon. Overall much nicer and fun than the museum of natural history. Plenty of dinosaur bones, shark teeth and other fossils on display. Not particularly modern, however.

(Translated by Google) Anyone passing by on the street will never imagine what the 19 of Rua da Academia de Ciências hides. The beautiful Geological Museum so little known and that has a very interesting and historic filling. It is the Noble Hall of the Academy of Sciences that is a real spectacle. It was great to go and show my grandson these places. (Original) Quem passar na rua nunca imaginará o que esconde o 19 da Rua da Academia de Ciências. O belo Museu Geológico tão pouco conhecido e que tem um recheio muito interessante e histórico. É o Salão Nobre da Academia das Ciências que é um verdadeiro espetáculo. Foi muito bom ir mostrar ao meu neto estes locais.

(Translated by Google) Some more updated attractions are missing. Especially for children, it must be something more attractive in the technological sense. (Original) Falta mais algumas atrações atualizadas. Principalmente para crianças, deve ser algo mais atraente no sentido tecnológico.

(Translated by Google) Hidden in Lisbon is a pearl to visit. Once again we had an excellent guide (Original) Escondido em Lisboa é uma perola a visitar. Mais uma vez tivemos uma guia excelente

We had a pleasant visit at the museum and saw a huge variety of fossils, minerals, crystals and artifacts. The only negative thing was that there was not as much information in English but if you don't want to know everything about every little specimen at the museum this place is worth a visit!

Marvellous place to go to and do not miss the classical concerts.
