No, it's true that that in particular is not a para-site, but just by doing a research you will find too many!

About the most official site ever of the Cenacolo, I don't get exactly if they have tweaked something recently, but the most functional site (in Italian and English) is

https://cenacolovinciano.org/en/

The one of the Ministry is indeed official, but still just links to this site, and, most importantly, for some arcane reason its English version lacks this link (but has an email adress). I hope this site will remain stable for now. There are still some loops to go through to reach the ticketing site (Visit -> How to book -> licensee link). For some reason, at the moment, availability seems to consider the current week only.

Thanks, Hubert! I have added them, they will show when the site is refreshed during the coming day.

The two links for Tusi sites are both invalid and on quick glance there isn't an official website :(

Thanks for checking! I've removed them

As mentioned in today's blog post, I have done some serious cleaning of the links on this website. This resulted in the situation that 84 WHS don't have a link to an "official" website anymore. Some may never had one, but it is good to have an updated overview. If you know of some suitable candidate links, please post them on this topic.

Volubilis
Not the official website, but it is worth to be added under "related", from Elizabeth Fentress, an archaeologist who co-directed excavations about 20 years ago:
https://sitedevolubilis.org/

It is from the National PR-centre, that sounds serious.



A couple more "Visite [name site]" websites...

Thanks Hubert, they have been added!

Sites from Spanish and Portuguese-speaking Countries. Almost all of them also have English and other languages as options of visualization.

Viñales valley: https://www.visitarcuba.org/vinales-cuba Tourism official (as everything in Cuba) page. No significant webpage from the local government.

Camino Real de Tierra Adentro: The only things I found are kind of sketchy. The only official things about the whole stretch are:
https://sic.cultura.gob.mx/ficha.php?table=patrimonio_humanidad&table_id=36&disciplina= It is general, and still, it is marked as related to Guanajuato state.
https://www.elcaminoreal.inah.gob.mx/ It is a general video, but it is from the INAH (Instituto Nacional de Antropología e Historia)
http://inahchihuahua.gob.mx/sections.pl?id=86 This one is official, but concentrating on the stretch of the Camino that passes through the state of Chihuahua. The main pdf document refers to both WHS and not WHS-Camino related sites in the state, some of which could be eventually added to the list (especially if the site is extended to New Mexico)
I think that, in this case, the best approach would be to find/list some official websites from component sites.

Camagüey: https://www.visitarcuba.org/camaguey Tourism official (as everything in Cuba) page.
https://www.municipio-cuba.com/municipio-camaguey.html The local government, sketchy.

Portobelo-San Lorenzo: https://es.tourismpanama.com/lugares-para-visitar/colon/portobelo/ Portobelo component
https://es.tourismpanama.com/lugares-para-visitar/colon/san-lorenzo/ San Lorenzo component
Both pages are from the official tourism board of Panama.

Ruins of León Viejo: https://www.visitanicaragua.com/las-ruinas-la-primera-ciudad-nicaragua/ Official tourism board.
Found this one https://www.visitleon.info/ruinas-leon-viejo.html from the municipality of León.

Paraty and Ilha Grande: https://visitbrasil.com/pt/2022/02/18/destino-paraty-rj-2/ Official tourism board.
https://www.paraty.rj.gov.br/a-cidade/sobre Local government (prefeitura)

Sewell Mining Town: https://www.chile.travel/donde-ir/destino/rancagua-y-sewell/ Official tourism board (also mentions Non WHS Rancagua)
https://www.fundacionsewell.org/visitasewell The foundation that manages the site

Church of Atlántida: https://turismo.gub.uy/index.php/lugares-para-ir/region-metropolitana/playas/atlantida From the official tourism board, much more focused on Atlántida as a beach town.
https://www.gub.uy/ministerio-educacion-cultura/comunicacion/noticias/iglesia-cristo-obrero-nuestra-senora-lourdesThis page is also official, and directly focusing on the church.
https://www.eladiodieste.org/fundaci%C3%B3n The webpage from the Eladio Dieste foundation. However, within the part of consultation of his works, only appears the "Iglesia San Pedro in Durazno". Most probably the website is still under construction.
https://www.sau.org.uy/fundacion-eladio-dieste-informacion/ This is from the Architectural Board of Uruguay, and the Eladio Dieste Foundation. It has opening times

Island of Mozambique:
Pretty surprisingly, the official national government webpage is pretty much lacking on specific information https://www.portaldogoverno.gov.mz/por/Cidadao/Informacao/Turismo. This one is much more complete, but lacking on specific information on Moçambique island: https://www.turismomocambique.co.mz/, in the attractions tab it includes "Mozambique" among the options, but the information there is general country information.
However, this local government page is way more complete https://www.ilhademocambique.co.mz/content/turismo I think it's the best webpage.

Noel Kempff Mercado National Park: ¡Pretty complete official webpage! http://sernap.gob.bo/noelkempffmercado/

Archipiélago de Revillagigedo: In the official Mexican Tourism Board webpage I found nothing, not even searching through the state the islands belong to (Colima).
However, this one, from México desconocido is more or less complete and tourist-oriented https://www.mexicodesconocido.com.mx/las-islas-revillagigedo.html
This is less tourist oriented, but is in the official page of the SEMARNAT (Environment and Natural Resources Secretary) https://www.gob.mx/semarnat/articulos/reserva-de-la-biosfera-archipielago-de-revillagigedo
This one is more like the news when the site was inscribed https://www.gob.mx/semarnat/articulos/archipielago-de-revillagigedo-patrimonio-mundial-de-la-humanidad?idiom=es#:~:text=Se%20localiza%20en%20el%20Oc%C3%A9ano,Ramsar%20por%20su%20importancia%20internacional.

Mbanza Kongo: It's official, but it's more of information on a tourist tour that visits Mbanza Kongo https://www.pa-angola-tourism.com/english/tours/m-banza-congo/ Couldn't really find anything else.

The official website for the Great Spa Towns of Europe is www.greatspatownsofeurope.eu.

The link under "Nomination website" doesn't exist anymore.

New website for the Langobards:

https://longobardinitalia.it/

It seems that it still has to be localised in other languages, but it's brand new.
