zyunro wo aruite, sakuhin wo kansyousi, satuei mo simasita.

In Japanese, を does not only mark a direct object. It can also mark the place or route that someone moves through.

So 順路を歩く means to walk along the route / follow the route on foot.

Common similar patterns are:

• 道を歩く = walk along the road
• 橋を渡る = cross the bridge
• 空を飛ぶ = fly through the sky

Here, 順路 is the path or course being followed, so を is natural.

順路 means the designated route, the prescribed course, or the official path to follow.

You often see it in places like:

• museums
• exhibitions
• tourist facilities
• buildings with a one-way flow

So in this sentence, it suggests something like following the marked route through an exhibit rather than just walking randomly.

鑑賞し comes from 鑑賞する, a する-verb meaning to appreciate / view / enjoy aesthetically.

The し here is the connective form of する, used to link actions in a list:

• 歩いて
• 鑑賞し
• しました

So the sentence is listing actions: walked along the route, viewed the works, and also took photos.

Why not 鑑賞して?
You could say 鑑賞して too. But 鑑賞し、撮影もしました sounds a bit more written, tidy, or formal. Japanese often uses this kind of mixed connective style in narration.

Yes, they are both linking one action to the next.

• 歩いて is the -て form of 歩く
• 鑑賞し is the connective form of 鑑賞する

Both connect clauses, but they have slightly different feel:

• -て is very common and neutral
• -し in this kind of list can sound a bit more formal or written

The main point is that only the last verb carries the full tense and politeness: しました.
The earlier verbs are linked forms leading up to that final verb.

Yes, it naturally suggests that order:

1. 順路を歩いて
2. 作品を鑑賞し
3. 撮影もしました

So the listener will usually understand it as a sequence of actions.

That said, Japanese clause-linking can sometimes just list related actions without focusing strongly on exact timing. But in this sentence, the most natural reading is a straightforward sequence.

鑑賞する is more specific and more formal than 見る.

• 見る = to see / to look at / to watch
• 鑑賞する = to appreciate something such as art, music, film, or a performance

So 作品を鑑賞する means more than just look at the works. It suggests viewing them thoughtfully or appreciatively, which fits a museum or gallery context very well.

も means also.

So 撮影もしました means also took photos or did photography as well.

It adds the idea that photography was one more thing done in addition to the other actions already mentioned.

Without も:

• 撮影しました = took photos

With も:

• 撮影もしました = also took photos

It can sometimes carry a slight nuance of that too, depending on context.

Yes, 撮影 is a noun, but it is also part of a する-verb:

• 撮影する = to photograph / to take photos / to film

This is very common in Japanese. Many Sino-Japanese nouns combine with する to function as verbs.

Examples:

• 勉強する = study
• 運動する = exercise
• 撮影する = do photography / take photos

So 撮影もしました is short for 撮影もしました from 撮影する in polite past.

Japanese very often omits the subject when it is clear from context.

So this sentence could mean:

• I walked along the route, viewed the works, and also took photos
• We walked along the route, viewed the works, and also took photos

Japanese leaves that unsaid unless it needs to be clarified. The listener is expected to understand it from the situation.

Not by grammar alone.

Grammatically, it simply means took photos or did photography too.

However, in real-world context, if someone says this about a museum or exhibition, it often implies that photography was possible or permitted there. That implication comes from the situation, not from the form もしました itself.
