Sul sito del museo c’è un link per prenotare la visita guidata di domenica.

Sul is the contracted form of su + il.

• su = on, on top of, on
• il sito = the website / the site
• su il sito becomes sul sito

This kind of contraction is very common in Italian with prepositions + articles:

• di + il = del
• a + il = al
• da + il = dal
• in + il = nel
• su + il = sul

So sul sito del museo means on the museum’s website.

Del is the contraction of di + il.

Here, di shows a relationship similar to English of or the apostrophe-s idea:

• il sito del museo = the museum’s website / the website of the museum

So:

• sito = site
• del museo = of the museum

Italian often uses di + article where English uses possession:

• la porta della casa = the door of the house / the house’s door
• il direttore del museo = the director of the museum / the museum’s director

C’è means there is.

It comes from ci + è:

• ci = there
• è = is

So:

• c’è un link = there is a link

This is the standard Italian way to say that something exists or is present somewhere.

Compare:

• C’è un link = There is a link
• Ci sono due link = There are two links

So in this sentence, c’è introduces the existence of the link on the website.

The apostrophe shows that ci is shortened before è.

• full form: ci è
• contracted form: c’è

In modern Italian, c’è is the normal written form in this expression.

The same happens in the plural?

• No, because the plural is ci sono, not a contracted form.

So:

• c’è = there is
• ci sono = there are

Yes, link is a borrowed English word, and it is very commonly used in Italian, especially for websites and technology.

So un link sounds completely natural in modern Italian.

You may also sometimes see more formal or less common alternatives, but in everyday Italian, link is the normal choice.

A learner should simply treat it as an Italian noun that happens to come from English.

Per + infinitive is a very common way to express purpose in Italian.

So:

• per prenotare = to book / in order to book

In the sentence:

• c’è un link per prenotare la visita guidata
• there is a link to book the guided tour

This structure is extremely useful:

• un posto per sedersi = a place to sit
• qualcosa da mangiare is different, but also common
• un numero da chiamare is also different in nuance

Here, per prenotare clearly explains what the link is for.

In Italian, adjectives usually come after the noun.

So:

• visita = visit / tour
• guidata = guided
• visita guidata = guided tour

This is the normal order in Italian.

Compare:

• un libro interessante = an interesting book
• una città bellissima = a very beautiful city
• una visita guidata = a guided tour

Sometimes adjectives can come before the noun, but that often changes the style or nuance. In this case, visita guidata is the standard expression.

Italian usually uses articles more often than English.

So where English can say:

• to book a guided tour
• to book the guided tour

Italian typically needs an article with the noun:

• prenotare la visita guidata
• or possibly prenotare una visita guidata, depending on the meaning

In your sentence, la visita guidata di domenica refers to a specific guided tour: the one on Sunday. That is why la makes sense.

Without an article, prenotare visita guidata would sound ungrammatical in standard Italian.

In this sentence, di domenica most naturally means for Sunday or the Sunday guided tour, depending on the context.

So:

• la visita guidata di domenica = the guided tour on Sunday / Sunday’s guided tour

However, learners should know that di domenica can sometimes mean on Sundays in more general statements:

• Di domenica il museo è aperto = On Sundays the museum is open

So why does it not mean on Sundays here? Because the sentence is about booking a specific visit, and la visita guidata di domenica sounds like one particular scheduled tour.

In other words, context makes the meaning clear.

Not naturally in this context.

Italian usually says:

• la visita guidata di domenica
• la visita guidata della domenica

Both can refer to the Sunday guided tour, though della domenica can sound a bit more explicitly tied to a specific Sunday slot or recurring Sunday event depending on context.

Using an adjective like domenicale here would sound unusual or too formal for normal museum information.

So di domenica is a very natural choice.

Italian word order is flexible, and the beginning of the sentence often shows what the speaker wants to emphasize first.

• Sul sito del museo c’è un link... puts the location first: On the museum website...
• C’è un link sul sito del museo... starts with the existence of the link: There is a link on the museum website...

Both are grammatical.

The version in your sentence sounds very natural because it first tells you where to find the link, which is probably the most useful information in context.

Because Italian usually does not need subject pronouns the way English does.

But in this sentence, the main point is even simpler: c’è is an existential expression meaning there is, so there is no separate subject pronoun like it or there in English grammar terms.

Italian often avoids extra pronouns unless they are needed for emphasis.

So you do not say something like:

• esso c’è un link — incorrect

You simply say:

• c’è un link

Usually, sul sito is the more natural choice for websites.

• sul sito = on the website
• nel sito = in the website

Italian often conceptualizes websites as surfaces or platforms you are on, much like English says on a website.

You may sometimes hear nel sito, especially when talking about content located inside the site in a more internal sense, but sul sito del museo is the most standard and natural phrasing here.

Un introduces something non-specific or newly mentioned:

• c’è un link = there is a link

Since the listener has not been told about this link before, Italian uses the indefinite article.

If both speaker and listener already knew which link was meant, then il link could be possible:

• Il link per prenotare non funziona = The link for booking doesn’t work

But in your sentence, the link is being introduced for the first time, so un link is the right choice.

You would use the plural ci sono instead of c’è.

For example:

• Sul sito del museo ci sono due link per prenotare la visita guidata di domenica.
• On the museum’s website there are two links to book the guided tour on Sunday.

You would also make the noun plural:

• un link → due link

Interestingly, link usually stays the same in the plural in Italian:

• un link
• due link

So the main change is:

• c’è → ci sono

A rough pronunciation guide is:

Sool SEE-to del moo-ZEH-o cheh oon link pehr preh-noh-TAH-reh lah vee-ZEE-tah gwee-DAH-tah dee doh-MEH-nee-kah

A few useful points:

• sito = SEE-to
• c’è sounds like cheh
• guidata begins with gw, roughly gwee-DAH-ta
• domenica = doh-MEH-nee-ka

And remember that Italian pronunciation is generally more regular than English spelling.
